Our take on the SanDisk 512GB microSDXC Memory Card for Nintendo Switch

This is SanDisk's officially licensed microSDXC card for the Nintendo Switch, sold in a 512GB capacity with UHS-I speeds rated up to 100MB/s read and 90MB/s write. The license means Nintendo has approved it for the console, and it carries a lifetime limited warranty in most regions. It suits Switch owners who download a lot of games and want one card to hold a large library. Rivals like Samsung Evo and Lexar Play cards match its speed class for less, but this one carries the official Switch branding and warranty.

Questions and answers

Is this card worth it over a cheaper microSD?
You pay extra for the official Nintendo license and the lifetime warranty. A Samsung Evo Select or Lexar Play card with the same U3 rating performs similarly for less, so the premium buys peace of mind rather than speed.
Will 512GB hold my whole Switch library?
It holds dozens of large games, but not every title you own. After formatting, usable space is a bit under 512GB, and games like Zelda or Call of Duty take a big share.
Does it work in a Switch Lite or Switch OLED?
Yes. All Switch models take microSDXC cards, and this one is licensed for the family. Insert it in the slot behind the kickstand or under the stand on the Lite.
Do I need to format it before use?
No. The Switch recognizes it and formats it automatically the first time you insert it. Move games over from internal storage in System Settings if you need space.
What speeds does it actually deliver?
SanDisk rates it at up to 100MB/s read and 90MB/s write, but the Switch's card reader caps real-world performance well below that. Load times are close to internal storage for most games.
Is there a warranty?
Yes, a lifetime limited warranty in the US and most regions, and 30 years in Germany and Canada. Keep the packaging or proof of purchase for a claim.
