The Nintendo Switch 2 ships with 256GB of internal storage, of which approximately 249GB is available after system software is accounted for. That is enough to begin building a game library, but modern releases can fill the console quickly.
Updates and downloadable content add to installation sizes, while some Switch 2 titles use Game-Key Cards that require the full game to be downloaded rather than run directly from the cartridge. Large examples include Final Fantasy VII Remake Intergrade at 90.4GB, Assassin’s Creed Shadows at 69GB and Resident Evil Requiem at nearly 29GB.
A microSD Express card can provide additional space for players with large digital libraries who want to avoid repeatedly managing their installed games. It may be unnecessary for users who mainly play smaller independent titles or keep only a few games installed.
Capacity should be chosen according to the size of the intended library. A 128GB card could lose more than half its space to a single 69.2GB game such as Split Fiction. A 256GB card offers storage comparable to another Switch 2 console and is described as a practical middle ground, while larger capacities provide more room. The console supports cards up to 2TB, although 1TB is currently the largest size mentioned as being available for purchase.
Prices can be substantial: a 256GB card costs around $60, while 1TB models can cost several hundred dollars. Cards from brands including SanDisk, Lexar and Samsung are reported to offer little difference in performance. Their main benefit is allowing more games to remain installed, rather than necessarily loading them faster than the console’s internal storage.
Older microSD cards from the original Nintendo Switch are not compatible for storing games on the Switch 2. Buyers need a microSD Express card, identified by the word “Express” or the “EX” logo. SanDisk’s “Extreme” branding does not indicate the same standard.
An old Switch microSD card can only be used to import screenshots and video clips from the original console to the Switch 2’s internal memory. It cannot store Switch 2 games or save data. Game saves remain in the console’s internal storage and cannot be copied to a microSD Express card.
Nintendo also recommends using a single card. Data stored across multiple cards cannot later be combined on one card, although it can be transferred from one card to a larger replacement. The system is therefore not designed for regularly swapping cards between libraries.
