Which microSD card works in a Switch or Switch 2?

Updated 2026-10-15 · facts checked 2026-10-15 · by the GameDealWave desk

Short answer: For an original Switch, Switch OLED or Switch Lite, a microSDXC card from 64GB up to 2TB is the usual choice. For a Nintendo Switch 2, buy a microSD Express card, because Switch 2 only saves and runs games from microSD Express.

Nintendo’s two console generations use different microSD rules, and the cards look almost identical in a listing photo. Before buying, the first question is not capacity or brand, it is which console the card is for.

What does the original Switch accept?

The original Nintendo Switch, the OLED model and the Switch Lite accept microSD (up to 2GB), microSDHC (4GB to 32GB) and microSDXC (64GB to 2TB) cards, according to Nintendo’s microSD FAQ. microSDXC cards need a system update the first time they are used, which the console handles when it is online. A microSD Express card also works in these consoles, but Nintendo notes it runs at ordinary microSD speed there.

In practice, most current cards sold for phones and cameras fit this description. A larger card means fewer deleted games, and digital-heavy libraries fill internal storage quickly.

What changed with Nintendo Switch 2?

Nintendo Switch 2 is compatible only with microSD Express cards, up to 2TB, for downloaded games, updates, DLC, screenshots and videos. Nintendo says the faster standard is needed so games run smoothly. Cards that support it carry the microSD “EX” symbol on the label, and the first use requires an internet system update.

Nintendo says an older microSD card can be inserted into a Switch 2 only to copy screenshots and videos to the system. It cannot be used for games. If you are upgrading from a Switch to a Switch 2, budget for a new card.

How do you read a microSD listing?

Card listings pack many logos into one title. The ones that matter:

• SDHC / SDXC: capacity families. SDXC covers cards above 32GB.
• UHS-I (Roman numeral I): a common bus interface on ordinary cards; it does not make a card microSD Express.
• U3, V30, A2: speed classes designed for cameras and phones. They are not Nintendo requirements, though faster cards often carry them.
• microSD Express / EX: the only cards that work for Switch 2 games.

When a listing offers several capacities, confirm which one is selected next to the purchase button. Product photos frequently show a different capacity from the one in the cart.

How much capacity is sensible?

Count the downloaded games you want installed together, not your whole library. Physical game cards store most of their data on the card, though many games still download updates to system storage. Digital-only players need the most space. A practical approach is to buy the largest card that fits your budget in the right type, rather than a bigger card of the wrong type.

What about fake or counterfeit cards?

Counterfeit memory cards can report a false capacity and lose data once full. Reduce the risk by buying from the brand’s own storefront or a listing sold and shipped by the retailer itself, and by testing a new card by filling it before trusting it with saves. Nintendo says game save data is stored in system memory and cannot be saved to a microSD card, but downloaded games and media are.

Mistakes to avoid

• Buying a regular microSDXC card for a Switch 2.
• Assuming a card that works in a phone is fast enough for Switch 2 games.
• Formatting a card in the console without first copying screenshots off it.
