Does this card work in the original Switch or a Steam Deck?

No. Those devices take standard microSD cards. The Switch 2 is the device that uses microSD Express, and this card is built for it.

How many games fit on 512GB?

SanDisk's own figure is up to 36 games on a 1TB card. At 512GB expect roughly half that, though it depends heavily on each game's install size.

Is it faster than a regular microSD card?

Yes. MicroSD Express uses a PCIe-based interface, and this card is rated up to 880 MB/s read, well above the roughly 100 MB/s of typical UHS-I microSD cards.

Does it come with a warranty?

Yes, a lifetime limited warranty.

Do I need to format it before use?

The Switch 2 formats a new card when you insert it, so back up anything already on the card first.

Our take on the SanDisk 512GB microSD Express Card for Nintendo Switch 2

This is a 512GB microSD Express card SanDisk builds and licenses for the Nintendo Switch 2. It uses the microSD Express interface the console requires, with rated read speeds up to 880 MB/s, so games load and worlds stream faster than on older UHS-I microSD cards. ThermAdapt keeps card temperatures in check during long sessions, and it carries a lifetime limited warranty. It suits Switch 2 owners who want a large library on the card; buyers with a Switch 1 or a camera should note those devices use standard microSD, not Express.
