Key takeaways
- Express format: The Switch 2 only accepts microSD Express cards, so a standard UHS-I or UHS-II card will not work for expanded game storage.
- Read speed: Look for read speeds around 880MB/s or higher, since faster cards shorten load times and keep large modern games responsive.
- Sustained write: Peak write numbers matter less than sustained write performance, which affects how quickly games install and downloads complete.
- Capacity: A 256GB card suits most players, while 512GB is the pick for those with large digital libraries who rarely want to delete titles.
- Brand reliability: Choose established memory makers with data recovery or warranty support, as storage failures can put your saved games and downloads at risk.
What's inside
The arrival of the Nintendo Switch 2 has made microSD Express the storage standard to know in 2026. Unlike the older UHS-I cards that worked in the original Switch, the Switch 2 requires the far faster microSD Express format, which uses an NVMe and PCIe interface to reach speeds that were previously impossible in such a tiny card. If you want to expand your handheld library, this is the only type of card that will do the job.
With several brands now competing on speed, capacity, and price, choosing the right microSD Express card comes down to matching sustained performance and storage size to how you play. This roundup covers the best microSD Express cards available now, all built to keep the Switch 2 and other modern devices loading quickly, so you can grow your game collection without the wait.
