512GB microSD Express for Nintendo Switch 2

This SanDisk card delivers 512GB of storage using the microSD Express interface with PCIe Gen 3. It is built for the Nintendo Switch 2 and targets players who need fast load times and ample space for large game libraries. The A1 and U3 ratings support smooth app performance and 4K video capture.

Upgrading from standard microSD cards

Standard UHS-I cards top out far below the 880MB/s read and 650MB/s write peaks this card reaches. The jump is worth it when moving to a platform that supports the Express protocol, such as the Switch 2, where sustained 220MB/s write prevents stutter during large installs or updates.

512GB capacity with sustained write headroom

The 512GB capacity comfortably holds dozens of modern titles, screenshots and video clips. Sustained write of 220MB/s keeps up with heavy download queues and direct capture. Buyers who want more storage for an extensive offline archive will need a larger card.

商品問答

Does the 0.59 x 0.43 x 0.04 inch card fit a standard microSD slot?

Yes, the microSD form factor matches the standard slot dimensions used in devices such as the Nintendo Switch 2.

What step is often missed when inserting this PCIe Gen 3 card?

Push the card until it clicks into the spring-loaded tray; a partial insert leaves the PCIe pins unseated and the drive invisible to the system.

How long before the 512GB A1/U3 card reaches its write-endurance limit?

Endurance varies with workload; the card sustains 220MB/s writes, so heavy continuous recording will wear it faster than light app storage.
