Description

TEAMGROUP High Endurance 64GB microSDXC – U3 V30 Memory Card for Continuous Video Recording

The TEAMGROUP High Endurance 64GB microSDXC is a durable UHS-I memory card designed specifically for recording-intensive applications such as compatible security cameras, monitoring systems, dash cameras and other devices that repeatedly write video to the memory card.

The exact THUSDX64GIV3002 model combines a 64GB microSDXC capacity with UHS Speed Class U3 and Video Speed Class V30, supporting a minimum sequential write class of 30MB/s under the relevant SD speed-class standard. TEAMGROUP rates the 64GB version for sequential speeds of up to 100MB/s read and 50MB/s write.

Unlike general-purpose microSD cards designed primarily for photos, file storage or occasional recording, TEAMGROUP's High Endurance range is engineered for repeated and long-duration video recording workloads. TEAMGROUP specifies the 64GB model for up to approximately 10,000 hours of Full HD 1920 x 1080 recording at a 26Mbps video bitrate under its test conditions.

The card is also designed for demanding environments, operating from approximately -25°C to 85°C and offering resistance to water, shock, static electricity and X-rays. It uses the microSDXC format with an exFAT file system and is covered by a 2-year limited TEAMGROUP manufacturer warranty.

Designed for Continuous and Repeated Video Recording

The main advantage of the TEAMGROUP High Endurance card over a conventional general-purpose microSD card is its focus on write-intensive recording workloads.

Security cameras, dash cams and monitoring devices can repeatedly record, delete and overwrite video as their storage becomes full. This creates a very different workload from occasionally saving photographs, documents or media files.

TEAMGROUP developed the High Endurance series specifically for professional and residential monitoring applications where consistent recording over long periods is important.

What Is a High Endurance microSD Card?

A high-endurance microSD card is designed for workloads that repeatedly write large amounts of data to flash memory.

Typical examples include continuous or event-based video recording where older footage may be overwritten automatically when the card becomes full.

This makes an endurance-focused card more appropriate than a basic general-purpose memory card for compatible devices that record frequently throughout the day.

Up to 10,000 Hours of Full HD Recording Endurance

TEAMGROUP rates the 64GB High Endurance model for up to approximately 10,000 hours of recording under its specified endurance test conditions.

The manufacturer's test reference is:

Resolution: Full HD 1920 x 1080
Video bitrate: 26Mbps
64GB endurance rating: Up to 10,000 recording hours

This figure describes the cumulative recording endurance used by TEAMGROUP for the card and should not be confused with the amount of video that fits on the card at one time.

Does 64GB Store 10,000 Hours of Video at Once?

No. The 10,000-hour figure is an endurance rating, not the card's one-time storage capacity.

A 64GB card cannot hold 10,000 hours of Full HD footage simultaneously. In a loop-recording device, older footage is normally overwritten as storage fills, allowing the same flash storage to be written repeatedly over its working life.

Is the 10,000-Hour Rating Guaranteed for Every Camera?

No. TEAMGROUP's 10,000-hour figure is based on Full HD 1920 x 1080 recording at a video bitrate of 26Mbps.

Actual endurance can vary according to video bitrate, resolution, recording pattern, temperature, camera behaviour, file-system activity and other operating conditions.

UHS-I U3 Performance

The TEAMGROUP High Endurance 64GB card uses the UHS-I interface and carries a U3 speed classification.

UHS Speed Class U3 indicates a minimum sequential write performance class of approximately 30MB/s under the relevant SD Association testing conditions.

This is particularly important for recording workloads because video needs a sufficiently consistent write speed to keep up with the stream of data generated by the camera.

Is This Card U1 or U3?

This exact THUSDX64GIV3002 model is U3.

TEAMGROUP's official product page identifies the High Endurance range as UHS-I U3 V30. If a third-party database describes this exact model as U1, that information conflicts with the manufacturer specification.

What Is the Difference Between U1 and U3?

U1 represents a minimum sequential write class of approximately 10MB/s, while U3 represents approximately 30MB/s.

The higher U3 classification is particularly relevant to higher-bitrate video recording and other workloads that require faster sustained writes.

V30 Video Speed Class

The card also carries the V30 Video Speed Class rating.

V30 represents a minimum sequential write class of approximately 30MB/s under the Video Speed Class standard.

TEAMGROUP specifically positions the card for compatible 4K and Full HD monitoring equipment.

What Does V30 Mean on a microSD Card?

V30 is a Video Speed Class developed for recording workloads. The “30” represents a minimum sequential write performance class of approximately 30MB/s.

It does not mean that the card's maximum write speed is only 30MB/s. TEAMGROUP rates this exact model for sequential writes of up to 50MB/s under suitable test conditions.

Up to 100MB/s Read and 50MB/s Write

TEAMGROUP rates the 64GB High Endurance model for:

Sequential read: up to 100MB/s
Sequential write: up to 50MB/s

The higher read speed can help when copying recorded footage from the memory card to a compatible computer or card reader, while write performance is especially important during video capture.

Will I Always Get 100MB/s Read Speed?

No. The 100MB/s figure is a maximum manufacturer rating rather than a guaranteed speed under every condition.

Actual transfer performance depends on the host device, card reader, USB interface, file size, operating system, workload and other hardware and software conditions.

Is the Write Speed 30MB/s or 50MB/s?

The figures describe two different things.

V30 / U3 indicate a 30MB/s minimum sequential write performance class under applicable standardised testing, while TEAMGROUP's up to 50MB/s figure is the card's maximum advertised sequential write performance.

Suitable for Compatible 4K Video Recording

TEAMGROUP specifies the High Endurance card as supporting 4K and Full HD video recording in compatible equipment.

The U3 and V30 classifications make the card suitable for recording modes whose storage requirement falls within the card's supported performance.

Will It Record 4K in Every Camera?

No memory card can guarantee compatibility with every 4K camera.

The camera or recording device must support:

64GB microSDXC cards
The exFAT / SDXC format or another supported device format
UHS-I media
The card's speed class
The selected recording bitrate and video mode

Always check the camera manufacturer's recommended card capacity and speed requirements.

Suitable for Security Cameras and CCTV Monitoring

The TEAMGROUP High Endurance series is specifically designed for professional and residential monitoring systems.

This can make the 64GB version suitable for compatible:

Indoor security cameras
Outdoor security cameras
WiFi cameras
IP cameras
CCTV cameras with local microSD recording
Video doorbells with supported microSD storage
NVR-related local camera storage
Other monitoring equipment using compatible microSDXC media

Will It Work in My Security Camera?

Compatibility depends on the exact camera.

Check that the device supports microSDXC cards of at least 64GB and does not require a different speed class, capacity limit or proprietary storage format.

Where possible, format the card inside the camera itself before beginning recording.

Suitable for Compatible Dash Cameras

High-endurance memory cards are also well suited to the workload created by compatible dash cameras because these devices often record continuously while driving and overwrite old footage when storage becomes full.

The TEAMGROUP High Endurance card's repeated-write design, wide operating-temperature range and U3/V30 performance make it relevant to this type of workload where the dash-cam manufacturer supports 64GB microSDXC storage.

Will This Work with Every Dash Cam?

No. Dash cams vary significantly in supported card capacity, file system and minimum speed requirements.

Some older models may support only microSDHC cards up to 32GB, while newer cameras may support 64GB, 128GB, 256GB or larger cards.

Always check the exact dash-cam model before purchase.

Useful for Continuous and Event-Based Recording

Not every monitoring device records video in the same way.

Some cameras record continuously, while others create clips only after motion, person, vehicle or sound detection.

The High Endurance card can be used in compatible systems employing either approach, but actual card lifespan and recording capacity will vary according to how frequently the device writes data.

64GB microSDXC Format

Because its capacity is 64GB, this product uses the microSDXC standard rather than microSDHC.

microSDXC covers capacities above 32GB, so the recording device must explicitly support SDXC / microSDXC storage.

Will a 64GB microSDXC Card Work in a Device That Supports Only 32GB?

No, not reliably. A device specified only for microSDHC or capacities up to 32GB should not be assumed to support a 64GB microSDXC card.

Always follow the host manufacturer's maximum supported capacity.

exFAT File System

TEAMGROUP lists the High Endurance microSDXC series as using the exFAT file system.

exFAT is the standard file system associated with SDXC storage and supports files larger than the 4GB limitation of FAT32.

Should I Format the Card Before Using It?

TEAMGROUP recommends formatting the memory card in the device in which it will be used, particularly for cameras and recording equipment.

This allows the device to create the file system, folders and recording structure it expects.

Formatting deletes existing data, so important files should always be backed up first.

What If My Camera Requires FAT32?

Some devices use non-standard requirements and may request FAT32 even for capacities above 32GB.

Follow the instructions supplied by the device manufacturer. The factory / standard microSDXC file-system specification for this card is exFAT.

Designed for Harsh Operating Conditions

Monitoring devices are often installed in locations exposed to temperature changes and other environmental stresses.

TEAMGROUP specifies the card for operation between approximately:

Operating temperature: -25°C to 85°C
Storage temperature: -40°C to 85°C

This wider operating range can be particularly useful for compatible outdoor cameras, in-car systems and other equipment exposed to varying temperatures.

Water, Shock, Static and X-Ray Resistance

TEAMGROUP designs the High Endurance card to resist several common environmental hazards.

The manufacturer specifically lists resistance to:

Water
Shock
Static electricity
X-rays
Extreme operating temperatures

TEAMGROUP also promotes dust and cold resistance for the High Endurance range.

Does Rugged Protection Make the Card Indestructible?

No. Resistance features reduce risk under specified conditions but should not be interpreted as meaning the card cannot be physically damaged.

Avoid bending the card, damaging its electrical contacts or exposing it to conditions outside the manufacturer's operating specifications.

Small 15 x 11 x 1mm microSD Form Factor

The memory card measures approximately:

Length: 15mm
Width: 11mm
Thickness: 1mm
Weight: Approx. 1g

This is the standard microSD-sized form factor used by many compact cameras and embedded recording devices.

2.7V to 3.6V Operating Voltage

TEAMGROUP specifies an operating voltage range of approximately 2.7V to 3.6V for the High Endurance microSDXC series.

Power is supplied automatically through the compatible memory-card slot; no external power connection is required.

Using the Card in a Full-Size SD Slot

The High Endurance card itself uses the microSDXC form factor.

A compatible microSD-to-SD adapter is required if you want to insert it into a full-size SDXC slot.

TEAMGROUP's exact product specification states that an adapter is required for full-size SDXC slots. An SD adapter should not be assumed to be included unless it is specifically listed or shown with the supplied retail package.

Designed for Recording Rather Than App Performance

The TEAMGROUP High Endurance 64GB card is optimised around endurance and video-recording performance.

TEAMGROUP does not list an A1 or A2 Application Performance Class for this exact High Endurance model.

Is This an A1 or A2 microSD Card?

No A1 or A2 rating is specified by TEAMGROUP for THUSDX64GIV3002.

A1 and A2 are application-performance ratings primarily relevant to random access workloads such as running applications from flash storage. They are different from the U3 and V30 classifications used for video recording.

Not a microSD Express Card

The THUSDX64GIV3002 is a conventional UHS-I microSDXC card. It is not a microSD Express / NVMe memory card.

If a device specifically requires microSD Express storage, a conventional UHS-I microSDXC card should not be substituted.

How Much Usable Storage Will 64GB Provide?

The capacity displayed by a computer or camera may be lower than the 64GB printed on the card.

TEAMGROUP defines 1GB as 1,000,000,000 bytes for product capacity, while operating systems may calculate and display storage using a different binary method. Some capacity is also used for formatting and file-system information.

This is normal behaviour for flash storage and does not mean part of the capacity is defective or missing.

Recording Time Depends on Camera Bitrate

The amount of video that fits on a 64GB card depends heavily on the recording bitrate rather than resolution alone.

Two cameras both described as “1080p” or “4K” can use significantly different amounts of storage if one records at a much higher bitrate.

Other factors such as frame rate, compression format, audio recording, event frequency and simultaneous video streams also affect storage consumption.

Will 4K Video Reduce Recording Time?

Usually, yes. Higher-resolution or higher-bitrate video generally creates larger files, reducing the amount of footage that can be held on the card before older files must be overwritten.

The exact difference depends on the camera's encoding settings.

Loop Recording and Automatic Overwriting

Many dash cams and surveillance cameras use loop recording. When the card becomes full, the device automatically deletes or overwrites older recordings to create space for new footage.

This repeated erase-and-write behaviour is one reason an endurance-focused card can be preferable to general-purpose storage in compatible recording systems.

Does the Memory Card Control Loop Recording?

No. Loop recording is a feature of the camera or recording device.

The memory card simply provides the storage used by the device. Check your camera settings to configure recording length, overwrite behaviour and protected-event recordings.

What Should I Check Before Buying?

Confirm the device supports 64GB microSDXC cards.
Check the required speed class.
This exact card is U3 and V30.
Confirm the device supports the microSDXC / exFAT format or can reformat the card appropriately.
Check whether the device manufacturer recommends high-endurance storage.
Check the maximum supported card capacity.
Confirm whether your recording bitrate is compatible with V30 storage.
If using a full-size SD slot, a suitable adapter is required.
Format the card in the target device where recommended.
Do not assume compatibility solely because the device has a physical microSD slot.

It combines high-endurance flash storage with UHS-I U3 and Video Speed Class V30 performance, offering sequential read speeds of up to 100MB/s and write speeds of up to 50MB/s.

Below are answers to the most common questions about TEAMGROUP High Endurance 64GB compatibility, dash cams, CCTV and security cameras, continuous recording, loop recording, 4K video, U3/V30 speed, endurance lifespan, exFAT and FAT32 formatting, card errors, recording reliability and microSDXC device support.

1. What is the TEAMGROUP High Endurance 64GB microSDXC card?

The TEAMGROUP High Endurance 64GB is a microSDXC memory card specifically designed for write-intensive video recording and monitoring applications. Unlike a general-purpose memory card, it is engineered for repeated recording and overwriting in compatible dash cams, CCTV cameras, security cameras and other monitoring devices.

2. What is the exact model number of this TEAMGROUP 64GB card?

The exact TEAMGROUP manufacturer part number is THUSDX64GIV3002. Checking the part number is useful because TEAMGROUP produces several different microSD ranges intended for different applications.

3. How much storage does the card provide?

The card has a manufacturer-rated capacity of 64GB. The usable space shown by a computer, camera or recorder will normally be lower because manufacturers use decimal capacity measurements while operating systems can display capacity differently, and some space is required for formatting.

4. Is this microSD, microSDHC or microSDXC?

This is a microSDXC memory card. SDXC covers SD and microSD capacities above 32GB, so the device must support microSDXC and a 64GB card rather than only older microSDHC cards.

5. What is the TEAMGROUP High Endurance 64GB card designed for?

TEAMGROUP designed this series for monitoring and long-duration recording environments. Typical uses include compatible dash cams, home security cameras, CCTV systems, IP cameras and other video recorders that repeatedly write and overwrite footage.

6. What does High Endurance mean on a microSD card?

High Endurance means the card is designed for workloads involving frequent or continuous writing rather than mainly storing files that rarely change. This makes it better suited to loop-recording cameras that continuously write new video and overwrite the oldest recordings when the card becomes full.

7. What is the difference between a High Endurance card and a normal microSD card?

A normal consumer microSD card may be designed mainly for photos, files, mobile storage or occasional video recording. A High Endurance card is designed specifically to tolerate repeated write-and-erase cycles generated by continuous or frequent video recording. This makes endurance cards the more appropriate choice for compatible dash cams and security cameras.

8. What is the endurance rating of the 64GB TEAMGROUP High Endurance card?

TEAMGROUP rates the exact 64GB model for up to 10,000 hours of recording at 26Mbps using Full HD 1920 x 1080 video under its test conditions. Recording endurance will vary with bitrate, resolution, codec, device behaviour and operating conditions.

9. Does 10,000 hours mean the card is guaranteed to fail after 10,000 hours?

No. The 10,000-hour figure is an endurance specification based on TEAMGROUP's stated 26Mbps Full HD test conditions. It is not a countdown timer or guaranteed failure point. Actual lifespan can be shorter or longer depending on the amount of data written and the operating environment.

10. Why does TEAMGROUP sometimes advertise up to 40,000 recording hours?

The High Endurance family includes several capacities. TEAMGROUP rates the 64GB version at up to 10,000 hours, 128GB at up to 20,000 hours and 256GB at up to 40,000 hours, based on 26Mbps Full HD 1080p recording. The 40,000-hour figure therefore applies to the 256GB model rather than this 64GB card.

11. Does a larger High Endurance card normally last longer?

Within this TEAMGROUP series, the official endurance ratings increase with capacity. The 64GB model is rated for 10,000 hours, the 128GB for 20,000 hours and the 256GB for 40,000 hours under the same stated recording conditions. A larger card also needs to cycle through its entire capacity less frequently during loop recording.

12. What is the maximum read speed of this card?

TEAMGROUP specifies a sequential read speed of up to 100MB/s. Actual transfer speed depends on the card reader, USB connection, host device, file size, software and other system conditions.

13. What is the maximum write speed of the TEAMGROUP High Endurance 64GB?

The card is rated for sequential write speeds of up to 50MB/s. Actual write performance varies according to the recording device, workload and operating conditions.

14. What does UHS-I mean?

UHS-I refers to the Ultra High Speed bus interface used by the card. To achieve the best transfer performance, the host device or card reader should also support a suitable UHS-I interface.

15. What does U3 mean on this microSD card?

U3 means UHS Speed Class 3. Under the SD Association speed-class standard, U3 indicates a minimum sequential write-speed class of 30MB/s under the specified test conditions. This is particularly useful for sustained video recording.

16. What does V30 mean?

V30 means Video Speed Class 30. It represents a minimum sequential video write-speed class of 30MB/s under the SD standard, making V30 suitable for demanding Full HD and many 4K recording applications where the camera's required bitrate is within the card's capabilities.

17. Are U3 and V30 the same thing?

They are separate SD speed-class standards, but both U3 and V30 correspond to a minimum sequential write-speed class of 30MB/s under their respective standards. V30 was developed specifically with modern video-recording workloads in mind.

18. Is the TEAMGROUP High Endurance 64GB suitable for 4K recording?

Yes. TEAMGROUP specifically states that the High Endurance series supports 4K and Full HD video recording, and the card carries a V30 speed classification. The recording device must also support microSDXC 64GB cards and its bitrate must be suitable for the card.

19. Is the card suitable for Full HD 1080p recording?

Yes. Full HD continuous recording is one of the applications for which the High Endurance series is designed. TEAMGROUP's published endurance test for the 64GB version is specifically based on 26Mbps Full HD 1920 x 1080 recording.

20. Is this 64GB TEAMGROUP card good for a dash cam?

Yes, provided the dash cam supports 64GB microSDXC cards and UHS-I U3/V30 storage. High-endurance memory is particularly appropriate for dash cams because loop recording continuously writes new footage and overwrites old footage.

21. Can it be used in a front-and-rear dual dash cam?

Potentially yes, provided the dash cam manufacturer supports 64GB microSDXC cards and the required speed class. Dual-camera systems can generate more data than single-camera models, so also check the dash cam's recommended card capacity, bitrate and recording specification.

22. Will this card work with a Nextbase dash cam?

It depends on the exact Nextbase model. Check the camera's manual for its maximum supported capacity and required card specification. If the model supports 64GB microSDXC U3/V30 cards, the TEAMGROUP card meets those basic storage-class requirements, but manufacturer-specific compatibility recommendations should still be followed.

23. Is this card suitable for CCTV cameras?

Yes, when the CCTV camera supports 64GB microSDXC cards. TEAMGROUP specifically designed this High Endurance series for professional and residential monitoring systems and repeated video recording.

24. Can I use the TEAMGROUP High Endurance 64GB card in a home security camera?

Yes, if the camera supports 64GB microSDXC storage. The high-endurance design is particularly useful for cameras configured for continuous recording or frequent motion-event recording.

25. Will this card work in a TP-Link Tapo camera?

It may work in Tapo cameras that support 64GB microSDXC storage, but compatibility varies between camera models and firmware versions. Check the exact Tapo model's supported capacity and card requirements before purchase and format the card through the Tapo camera or app where instructed.

26. Why can a 64GB card work in one Tapo camera but not another?

Different camera generations can have different capacity, filesystem, firmware and card-controller requirements. This is why a card working normally in a computer or another camera does not automatically guarantee compatibility with every Tapo model. Always check the exact camera's specifications and update its firmware if necessary.

27. Can the TEAMGROUP High Endurance card be used in a Wyze camera?

Potentially yes if the exact Wyze model supports a 64GB microSDXC card. High-endurance cards are commonly selected for cameras using continuous recording, but supported capacities and formatting requirements vary by camera generation.

28. Can I use it in an Eufy security camera?

Yes where the specific Eufy model provides a compatible microSDXC slot and supports 64GB capacity. Check the Eufy product manual because some Eufy cameras use microSD storage while others use HomeBase or different storage arrangements.

29. Can this card be used in Reolink or other IP security cameras?

Potentially yes. Many IP cameras provide microSDXC recording, but maximum capacity and required formatting vary by model. Confirm that the exact camera supports a 64GB microSDXC UHS-I card before installation.

30. Is this card suitable for continuous 24/7 recording?

Continuous and long-duration recording is one of the main workloads for which TEAMGROUP designed its High Endurance series. Actual card lifespan depends on recording bitrate, resolution, codec, temperature and how frequently the device rewrites the storage.

31. Is it suitable for motion-detection recording?

Yes. Event or motion recording generally writes less total data than continuous recording, although this depends on how frequently motion events occur. A high-endurance card remains useful because security-camera workloads can involve frequent repeated writes over long periods.

32. What is loop recording?

Loop recording allows a camera or dash cam to continue recording after the memory card becomes full by automatically deleting or overwriting the oldest unlocked footage. This repeated writing is one reason high-endurance cards are recommended for compatible monitoring equipment.

33. Does the card automatically delete old recordings when it becomes full?

The memory card itself does not manage your recordings. Loop recording is controlled by the dash cam or security camera. If your device supports loop recording, it can overwrite older footage when storage is full while protected or locked clips may be handled separately.

34. Is 64GB enough for a dash cam or security camera?

64GB can be suitable for many cameras, but recording time varies considerably according to resolution, bitrate, codec, number of cameras and whether recording is continuous or event-based. Higher-resolution or multi-camera systems fill the card faster than a single Full HD camera.

35. How many hours of video can a 64GB card store?

There is no single recording-time figure because video file size depends primarily on bitrate. Two 1080p cameras can use very different amounts of storage depending on compression and quality settings. Check your camera manufacturer's recording-time table or bitrate specification for the most accurate estimate.

36. Should I choose 64GB, 128GB or 256GB for continuous recording?

Choose a capacity supported by your recording device. Larger cards hold more footage before loop recording overwrites older files and the TEAMGROUP High Endurance range also has higher published endurance ratings at larger capacities. The 64GB version is rated at 10,000 hours, 128GB at 20,000 hours and 256GB at 40,000 hours under TEAMGROUP's stated Full HD test conditions.

37. Why does my 64GB card show less than 64GB of usable space?

This is normal. Storage manufacturers specify capacity using decimal units while operating systems can display storage differently. Formatting and filesystem information also use a small amount of space, so the usable capacity displayed will be lower than 64GB.

38. What filesystem does the TEAMGROUP High Endurance 64GB use?

TEAMGROUP lists the 64GB High Endurance microSDXC card with exFAT formatting, which is the standard filesystem commonly associated with SDXC cards.

39. Should I format the card before using it in my camera?

Yes. TEAMGROUP recommends formatting the memory card in the target device before use where possible. Formatting it through the dash cam, security camera or camcorder helps the device create the filesystem and folder structure it expects. Formatting erases existing data, so back up anything important first.

40. Should I format the card in the camera or on a computer?

Where the camera offers its own formatting function, formatting in the target device is normally preferable because it uses the filesystem and structure expected by that device. TEAMGROUP specifically advises formatting its memory cards on the intended device to help ensure functionality and integrity.

41. Can a 64GB TEAMGROUP card be formatted as FAT32?

Although SDXC cards are normally supplied as exFAT, some older or particular devices may require FAT32. Only reformat the card to FAT32 if your device manufacturer specifically requires it. Formatting erases all existing files, and device compatibility should always take priority over using a particular filesystem.

42. Should I use FAT32 or exFAT for my security camera?

Use the filesystem recommended by the exact camera manufacturer. The TEAMGROUP 64GB card is supplied as exFAT, but some cameras reformat cards internally or require a different filesystem. Do not assume that one format is correct for every security camera.

43. Why does my camera say it cannot format the microSD card?

Possible causes include unsupported card capacity, incompatible filesystem, outdated camera firmware, poor card contact, an incorrect card type or a problem with the camera's microSD slot. Check the device's supported capacity first, update its firmware and try its built-in format function before assuming the card is faulty.

44. Why does the card work in my PC but not in my security camera?

A computer can support a wider range of filesystems and storage capacities than some embedded cameras. A card can therefore be completely readable on a PC while still being rejected by a camera because of capacity, filesystem, firmware or device-specific compatibility restrictions.

45. What should I do if my camera does not detect the TEAMGROUP card?

Power down the device where required, remove and firmly reinstall the card, confirm that the camera supports 64GB microSDXC storage, update its firmware and then use the camera's own format function. TEAMGROUP also recommends checking device firmware and formatting the card in the target device when detection or stability problems occur.

46. Do I need to regularly reformat a dash-cam or CCTV memory card?

Follow the recording-device manufacturer's maintenance recommendation. Some dash-cam and camera manufacturers recommend periodic in-device formatting, while others manage loop recording automatically. Formatting deletes recordings, so save any required footage first.

47. What can cause microSD card corruption in a dash cam?

Possible causes include interrupted power during writing, unsafe card removal, overheating, filesystem corruption, worn flash memory, device firmware issues, incompatible storage capacity or a failing card reader or camera slot. A high-endurance card reduces wear-related risk but cannot prevent every possible recording-system failure.

48. Can a bad power supply make a dash-cam memory card appear faulty?

Potentially. Sudden power interruptions while a camera is writing data can damage incomplete files or the filesystem. If repeated card corruption occurs, check the dash cam's power supply, cable, vehicle power adapter and shutdown behaviour as well as the memory card itself.

49. Can I remove the card while the camera is recording?

It is better to stop recording or power down the device according to its instructions before removing the card. Removing storage while data is being written can corrupt the current recording or filesystem.

50. What does it mean if a microSD card becomes read-only or write-protected?

A card that can still be read but can no longer be written may have a filesystem problem or its internal flash controller may have detected a serious memory condition. Back up any readable recordings immediately and test the card before continuing to rely on it for security or dash-cam recording.

51. How can I check whether the card is genuine and really 64GB?

Buy from a trusted retailer and verify the TEAMGROUP part number and packaging. If required, reputable full-capacity testing software can write and verify the entire card. Counterfeit cards can falsely report a larger capacity and begin corrupting files once their real physical capacity is exceeded.

52. What is the operating temperature range of the TEAMGROUP High Endurance card?

TEAMGROUP specifies an operating temperature range of -25°C to 85°C. This wide range is particularly useful for dash cams and outdoor monitoring equipment exposed to hot or cold environments.

53. What is the storage temperature range?

TEAMGROUP specifies a storage temperature range of approximately -40°C to 85°C.

54. Is the TEAMGROUP High Endurance card waterproof?

TEAMGROUP lists the High Endurance series as resistant to water as part of its protection features. This provides additional physical resilience, but important footage should still be backed up because no removable flash storage should be treated as the only copy of critical data.

55. Is the card shock resistant?

Yes. TEAMGROUP lists resistance to shock among the High Endurance series' durability features, helping the card cope with demanding monitoring environments such as vehicle recording.

56. Is the card resistant to X-rays?

Yes. TEAMGROUP specifies X-ray resistance as one of the card's protection features, which can be useful when travelling through environments such as airport security screening.

57. Is the TEAMGROUP card resistant to static electricity?

Yes. TEAMGROUP includes resistance to static electricity among the protective characteristics of its High Endurance series.

58. What are the dimensions and weight of the card?

The card measures approximately 15 x 11 x 1mm and weighs approximately 1g, which is the standard microSD form factor used by compatible microSDXC devices.

59. What operating voltage does the TEAMGROUP High Endurance card use?

TEAMGROUP specifies an operating voltage range of approximately 2.7V to 3.6V.

60. Can I use the microSD card in a full-size SD card slot?

Yes, if you use a compatible microSD-to-SD adapter and the device supports SDXC cards. TEAMGROUP states that an adapter is required when using the microSDXC card with a compatible full-size SDXC slot.

61. Why am I not getting 100MB/s when copying files?

The 100MB/s figure is an “up to” sequential read specification. Actual performance depends on the card reader, USB interface, host device, computer, file sizes, filesystem and software. A slow USB port or card reader can become the performance bottleneck.

62. What kind of card reader should I use?

Use a good-quality card reader that supports microSDXC and UHS-I if you want the best PC transfer performance. TEAMGROUP specifically notes that an appropriate professional card reader is recommended for optimal transfer speeds.

63. Does this card have an A1 or A2 Application Performance rating?

TEAMGROUP does not list an A1 or A2 Application Performance Class for this High Endurance model. Its key ratings are UHS-I U3 and Video Speed Class V30 because it is primarily designed for sustained recording rather than running mobile applications from the card.

64. Can I use this card in an Android phone or tablet?

Potentially yes if the device supports 64GB microSDXC cards, but this model is optimised for endurance and video recording rather than app performance. For ordinary mobile storage, a TEAMGROUP card with an A1 or A2 application rating may be more appropriate.

65. Can I use the TEAMGROUP High Endurance card in a GoPro or action camera?

Potentially, provided the exact camera supports 64GB microSDXC UHS-I U3/V30 cards and its required recording bitrate is compatible. Action-camera manufacturers often publish specific card requirements or compatibility lists, so check the camera model before purchase.

66. Can I use this card in a drone?

It may work in drones that support 64GB microSDXC U3/V30 storage, but the exact drone's recording bitrate and recommended memory-card specification should be checked first. This model is primarily optimised for monitoring and endurance workloads.

67. Can I use this card in a Nintendo Switch, Steam Deck or Raspberry Pi?

It can potentially function in devices that support 64GB microSDXC storage, but this is not its main intended purpose. The High Endurance model is optimised for repeated video recording and has no advertised A1/A2 app-performance rating, so a general-purpose or application-rated microSD card may be better for gaming handhelds or operating-system storage.

68. Does TEAMGROUP specify whether this card uses TLC or MLC NAND?

TEAMGROUP's current public specification for THUSDX64GIV3002 does not identify a particular TLC or MLC NAND type. It is therefore better to rely on the manufacturer's published High Endurance rating, speed specifications and warranty rather than assuming an undocumented NAND technology.

69. Does TEAMGROUP publish a TBW rating for this memory card?

TEAMGROUP does not publish a conventional SSD-style TBW figure for this card. Instead, the manufacturer provides a recording-endurance rating, with the 64GB version rated for up to 10,000 hours at 26Mbps Full HD 1080p under its stated test conditions.

70. What warranty does the TEAMGROUP High Endurance 64GB card have?

The High Endurance microSDXC series carries a 2-year limited manufacturer warranty, subject to TEAMGROUP's warranty terms. Keep your proof of purchase in case warranty support is required.

71. Is the TEAMGROUP warranty intended to cover surveillance use?

This product is specifically marketed by TEAMGROUP as a High Endurance surveillance and monitoring memory card. TEAMGROUP's general warranty notes distinguish surveillance memory cards from ordinary cards when discussing exclusions for continuous video-recording equipment.

72. Who should NOT buy the TEAMGROUP High Endurance 64GB card?

This card is not suitable for devices limited to 32GB microSDHC cards, devices that do not support microSDXC, or users needing more than 64GB of recording capacity. It is also not the most logical choice if your main requirement is smartphone app storage, gaming storage or another workload where an A1/A2 application-rated card would be more useful than high recording endurance.

73. Why choose a High Endurance card instead of a cheaper standard microSD card for CCTV or dash cams?

Dash cams and surveillance cameras repeatedly write and overwrite large amounts of video. This creates a much heavier flash-memory workload than storing photos, music or occasional files. The TEAMGROUP High Endurance series is specifically designed for this type of write-intensive monitoring workload, making it a more appropriate choice than an ordinary general-purpose card.
