Nintendo Switch 2 storage

The Switch 2 has 256 GB inside. The card slot is the way to add room, and it has one rule to know before you buy: the card must be a microSD Express card.

Before you buy a card

  • Look for the word Express on the card and on the package. A card without it will not run Switch 2 games.
  • Check any card you bought for a first Switch: if it does not say Express, it will not run Switch 2 games.
  • Capacity goes up to 2 TB, so the size you pick is a question of budget and of how many games you keep.

If you still play an earlier Switch

The original Switch and the Switch OLED take ordinary microSD, microSDHC and microSDXC cards, so a used bundle for one of those models may come with a card that suits it.
