Top SD Cards for Nintendo Switch 2

For anyone picking up a Nintendo Switch 2, the question of expandable storage is unavoidable. Digital downloads are the norm today, and while the original Switch made adding space relatively affordable, the new system changes everything. The Switch 2 exclusively supports microSD Express cards, a much faster and far more expensive standard than what came before. Options are limited, prices are high, and finding the right balance between cost and capacity requires careful thought. This guide covers the best microSD Express cards currently available for the Switch 2, along with practical strategies to stretch your storage budget.

The reason these new cards carry such a premium comes down to two factors: performance and scarcity. microSD Express cards boast dramatically faster read and write speeds compared to standard SD cards. This allows the console to load larger game assets more quickly, which is likely essential for maintaining performance in many Switch 2 exclusive titles. Even backward-compatible Switch 1 games can benefit from faster loading. However, because the Switch 2 is one of the very first devices to require this technology, production volumes are low. This low supply is compounded by massive demand from AI data centers, which consume the vast majority of high-speed memory components before they reach retail. As a result, don’t expect prices to drop significantly anytime soon.

When shopping for a card, stick with trusted brands. Samsung, Lexar, and SanDisk are the safest bets for reliability. Off-brand storage carries a higher risk of failure, and losing a card loaded with save data,especially for games like Pokémon that lack cloud saves,is a nightmare you want to avoid. GameStop’s in-house branded cards are also a solid option. Currently, the largest capacity available is 1 TB, and it comes at a steep cost. For example, Lexar’s 1 TB card recently jumped from $200 to around $350. Many off-brand 1 TB options exist, but their reliability is unproven.

For most users, the sweet spot is SanDisk’s 512 GB microSD Express card, currently priced around $120. It offers a good balance of usable space and reasonable cost. If you need maximum capacity and are willing to pay for it, the Lexar 1 TB card is the premium choice that many early adopters grabbed at launch.

Even a 1 TB card can fill up fast. Many Switch 2 games are massive, with titles like Cyberpunk 2077: Ultimate Edition requiring over 60 GB. A smart workaround is to split your library between physical and digital purchases. If a game takes up more than 15 GB, buying a physical cartridge that contains the full game saves significant internal or SD card space. This doesn’t work for “game-key cards” that are just download codes, but for true physical releases, it’s a reliable strategy. Here are some Switch 2 titles worth grabbing physically to save space:

• Mario Kart World (23.4 GB)Note: The Breath of the Wild* Switch 2 Edition requires an additional 2-3 GB download because the DLC is not on the cartridge.Most of these physical games will receive updates over time, but those patches are generally small. Kirby Air Riders, for instance, is a great candidate for a physical purchase since it has no planned DLC or major content updates, meaning the cartridge will hold nearly all of the game’s content indefinitely.What storage-saving tricks do you use?
