SanDisk 400GB Ultra microSDXC 120MB/s - $59.99

I bought this a week ago for my switch as well, ran h2testw on it, seems to be a legit card (sold and shipped by amazon)

only thing is, I ran crystal disk and it showed 20 mb/s read+write which seems to be pretty low performance (it might be my MSI laptop port tho), for the switch, I don't see a difference and it works well

I would probably not use this in a high end DSLR since it might be too slow for big raw pictures

Bit off topic, but does anyone know where to find good deals on XQD or CFexpress cards? Need them for my Nikon Z6

You should be getting up to 100MB/s read.
Sandisk rated this microSDXC as Speed Class 10, UHS Speed Class 1 and A1 so minimum sequential write speed is 10MB/s

Yes, Ultra is not good for DSLR's

Be careful.

There are two UHS interfaces called: UHS-I, and UHS-II.

But there are two UHS Speed classes: designed with symbols that look like "U1" and "U3". This corresponds to V10 and V30

You can have a UHS-I card with V10/U1 or a UHS-I card with V30/U3 speeds.

All devices are compatible with UHS-I, so mostly a person should just look at whether there is a U1 or U3, or V10, V30, V60 to identify the speed. UHS-II cards are much higher speed and you may find high end cameras that support UHS-II.
