I bought this for the Nintendo Switch 2 and I have no doubts it'll work well due to SanDisks reliability. I was however disappointed to see that this microSD Express card does not come with an adaptor in the box. I have an old one I can use, but it won't reach the speeds this microSD is capable of.

Fabulous product. Works fabulous. Works well on my switch 2

I can confirm advertised speeds are achievable. You WILL need the SanDisk - PRO-READER SD Express (sku: 6633042) and, in my case, an Insignia Thunderbolt 4 cable (sku:6540038) plugged into a usb 3.2 gen 2 port. This will work in any device accepting a UHS/v30/xci/3a2 card, such as a gopro or phone. It can also be used in a non-express reader, though, your read speeds will be 153MB/s and 106MB/s write.

I've been using the SanDisk Extreme 2256 gb card for a month now, and it has exceeded my expectations in every way. This card is fast. I haven’t run into any stuttering or lag when loading larger titles. The Switch 2 seems to take full advantage of the card's speed. If you’ve got a Switch 2 and need extra space, this SanDisk 256GB microSD card is an easy recommendation. Fast, reliable, and plenty of room for your games without needing to constantly delete or shuffle files around.

Works great, fast load times and doubles my switch 2 storage. Hard to argue against it at this price.
