FAQ: Frequently Asked Questions

FAQ — SanDisk 256GB microSD™ Express Card (SD 7.1)

1) What speeds does this SanDisk microSD™ Express card reach?
Up to 880 MB/s read and 650 MB/s write on a microSD/SD Express-compatible device or reader. In UHS-I devices it will run at normal UHS-I speeds.
2) Is it compatible with Nintendo Switch™ 2?
Yes. SanDisk confirms this card works with Nintendo Switch™ 2 and is designed to deliver faster game load times on the console’s microSD Express slot.
3) Will it work in current Switch, Steam Deck, phones, cameras, or drones?
Yes. microSD Express cards are backward-compatible with UHS-I hosts, so they function like a normal microSD card in today’s devices (at UHS-I speeds).
4) What is “microSD Express (SD 7.1)” and why is it faster?
It uses a PCIe Gen3 x1 + NVMe interface instead of the older SD bus, enabling SSD-class throughput; the SD 7.1 spec allows up to 985 MB/s theoretical bandwidth.
5) Do I need a special reader or slot to see 880/650 MB/s on a PC?
Yes. Use a microSD/SD Express–capable slot or a pro reader that supports SD Express; standard UHS-I/II readers cap performance to UHS-I. SanDisk cites its PRO-READER SD Express Dual Card as a compatible option.
6) Is this card good for high-resolution video?
SanDisk markets the microSD Express line for high-bitrate capture (up to 5.3K today) and very fast offloads when paired with an SD Express reader—ideal for creators using drones, action cams, or phones that support the format.
7) What capacity options exist in this SanDisk series?
SanDisk lists 128GB, 256GB, and 512GB microSD™ Express models in the same family.
8) What comes in the box? Is an adapter included?
“In the box” is the SanDisk microSD™ Express card itself. SD or USB readers/adapters are sold separately.
9) How durable is it?
SanDisk specifies protection against water, temperature, humidity, drops, shock, magnets, and X-rays, plus wear-out protection—built for travel and field use.
10) What warranty does SanDisk provide?
The microSD Express line carries a limited lifetime warranty (region-dependent).
11) Will microSD Express replace UHS-II? What’s the difference?
UHS-II speeds up the SD bus with a second pin row; microSD Express switches to PCIe/NVMe, which scales to much higher throughput while keeping backward compatibility with UHS-I devices.
12) Do I need to format the card for Switch 2?
When you first insert the card, the console may prompt to format it for best performance—follow the on-screen steps. (This is standard practice for Nintendo consoles; exact prompts depend on system software.)
13) How does this compare to older ‘Switch microSD’ cards?
Traditional UHS-I microSD tops out around ~100 MB/s; microSD Express (SD 7.1) can be multiple times faster, which reduces load times on supported hardware like Switch 2 and speeds up transfers on SD Express PCs/readers.
14) Is microSD Express widely supported yet?
Support is rolling out: Switch 2 uses it, and SD Express readers/slots are appearing in pro gear and new PCs. Backward compatibility means you can buy now and use it at UHS-I speeds until you upgrade your host.
