Extra storage for a Nintendo Switch 2 or other compatible device, these 256GB microSD Express cards sit at the top end of the microSD range, competing with standard microSDXC cards that prioritise capacity over speed. The SanDisk version is branded for Nintendo Switch 2, while the Samsung option is a more general equivalent. The key point is the “Express” part, it’s aimed at devices that can take advantage of higher transfer speeds, which can help with big game downloads, faster installs and moving captures or saves between consoles and a PC.

Do you actually need microSD Express?

If your device supports microSD Express, it’s a sensible upgrade over regular microSD, especially if you’re regularly installing and deleting large games. If it doesn’t, you’ll still get the capacity, but you won’t see the headline speed benefits.

  • 256GB capacity: enough for a decent library without constantly juggling installs.
  • microSD Express format: targets faster loading and transfer performance on supported hardware.
