The Nintendo Switch 2 requires a microSD Express card for game storage. A regular UHS-I microSD card will not work for Switch 2 games, so the Express marking is the one spec that matters. Capacities run up to 2TB. Because these cards are small and pricey, we show the absolute price and the price per gigabyte side by side, so you can see real value rather than just the sticker. This table lists only genuine microSD Express cards on Amazon.com, ranked by price per gigabyte.

Frequently asked questions

What memory card does the Switch 2 use?

A microSD Express card. Standard UHS-I microSD cards do not work for Switch 2 games; only Express cards have the speed the console requires.

Will my old Switch microSD work in the Switch 2?

Not for games. Older UHS-I cards are not fast enough for Switch 2 titles. You need a microSD Express card.

What size microSD Express should I buy?

256GB or 512GB are the common picks; 1TB and 2TB exist for big libraries. Sort by price per gigabyte to find the best value.
