Who it’s for / pitfalls
Good for
- Nintendo Switch 2 owners adding game storage
- Anyone with a microSD Express slot who wants faster reads
Not for
- People with only a standard UHS-I slot and no Switch 2, who won't see the extra speed
Known pitfalls
- In a UHS-I device the sequential read is 90 MB/s; 800 MB/s needs microSD Express support
- Samsung's 800 MB/s figure comes from the 512GB card on a PCIe test board, so real speeds vary
- The US page lists 5 m drop protection, while the China page lists 1 m drops repeated 10 times
