On a microSD Express memory card, you can store demanding media files and games. These memory cards use NVMe, so they work faster than regular microSD cards. Thanks to this, you can open large files up to 10 times faster. You can also record 4K images more smoothly thanks to the higher write speed. You can also use a microSD Express card in a Nintendo Switch 2. Newer games start faster from a microSD Express card than from a regular microSD card.
