SANDISK 512GB microSD Express Card - Works with Nintendo-Switch 2, Up to 880MB/s Read, Up to 650MB/s Write, 220MB/s Sustained Write, U3, C10 - SDSQXFN-512G-GN4N

The SanDisk 512GB microSD Express card is expandable storage for Nintendo Switch 2, suited to players who want room for a large game library and fast transfers, with read speeds up to 880MB/s and write speeds up to 650MB/s.

Recommended For

• Nintendo Switch 2 players with a mostly digital library who want to keep more downloaded games, updates, and DLC installed instead of repeatedly deleting and redownloading software.
• Switch 2 owners who want extra storage for downloaded games and game-key-card downloads; the card is officially licensed for the console and is designed to run games directly from the card.
• Portable Switch 2 players who want a larger selection of installed games available while traveling, without relying on an internet connection to redownload titles after deleting them.
• Switch 2 users who also save many screenshots or video captures and want those files stored on expandable memory alongside software.

Real-World Use Scenarios

• When the Switch 2’s built-in storage starts filling up, use the card to keep more downloaded games installed at once, reducing the need to delete and later redownload titles. SanDisk estimates about 18 average-sized games on its 512GB card; actual counts vary by game.
• For games stored on the card, launch and play them directly from it rather than moving each title back to system storage first. A hands-on SanDisk review reported no noticeable slowdown in tested games, though loading times can vary by title and internal storage may be faster in some tests.
• If you have a standard microSD card from the original Switch, use this microSD Express card for Switch 2 game storage instead. Nintendo says older, non-Express cards can transfer Switch screenshots and videos, but cannot save or load digital games on Switch 2.
• When system storage is tight, move a large installed game to the card to make room without deleting it. Transfers take time—a TechRadar test took about 14 minutes to copy a 60.5GB game to a SanDisk microSD Express card—so this is useful for managing space, not an instant swap.
• For portable play away from reliable Wi-Fi, keep the games you expect to play installed on the card before traveling. That gives the console access to those stored titles without needing to redownload them on the trip; the card adds storage but does not replace an internet connection needed for online play or downloads.
