Manufacturer Contact Info

The Team Group APEX SD7.1 is a 256GB microSD Express card for gamers and creators who want fast storage for compatible devices, with read speeds up to 800MB/s and write speeds up to 700MB/s when used with professional card readers.

Recommended For

Nintendo Switch 2 owners who want extra space for downloaded games, screenshots, and videos; Nintendo specifies microSD Express for these uses, and this card supports that format.
Switch 2 players who move large files using a MicroSD Express-compatible card reader; the card is rated for up to 800 MB/s read and 700 MB/s write with professional readers.
Portable gaming handheld owners who need removable storage and whose device supports MicroSD Express—or who are content using the card through its backward-compatible UHS interface.

Real-World Use Scenarios

On a Nintendo Switch 2, use the card to add space for downloaded games, screenshots, and video clips when the console’s internal storage fills up. Games can be played from the card, though some may load a little faster from internal storage.
When a Switch 2’s internal storage is nearly full, move a large downloaded game onto the card to free space. In one review of this APEX model, transferring a 60.5GB game took about 18 minutes, so allow time for large moves.
On a Steam Deck, use the card to keep more games installed without using as much internal SSD space. The Deck can run games from microSD, but this card operates at UHS-I speeds in that type of device, and loading screens may take longer than from the internal drive.
For copying files to or from a PC, pair the card with a microSD Express-compatible reader to access its higher-speed mode. In a UHS-I reader or older compatible device, transfers are limited by that device’s interface rather than the card’s Express rating.
