Our take on the SanDisk Ultra MicroSDXC Class 10 UHS-I U1 A1 120MB/s 512GB + SD Adapter

The SanDisk Ultra is a 512GB microSDXC card with UHS-I speeds up to 120MB/s read, rated Class 10, U1 and A1. It is the mainstream tier of SanDisk's card line: fast enough for 1080p video, photos and app storage on Android phones, but not built for sustained 4K recording or action cameras. It ships with an SD adapter for laptops and card readers. Owners rate it highly for everyday use; the common caveat is that write speeds are far below the read figure, so large file transfers take longer than the headline suggests.

Questions and answers

Is this card fast enough for 4K video?
It is rated U1, which suits 1080p recording. For 4K in a phone or camera, a U3 or V30 card is the safer choice.
Will it work in a Nintendo Switch?
Yes. The A1 rating and 512GB capacity make it a common pick for Switch game storage.
What is the difference between the read and write speed?
The 120MB/s figure is read speed, used when copying files off the card. Write speed, when saving files, is lower and not stated on the label.
Does it come with an SD adapter?
Yes. The package includes a full-size SD adapter so the card fits standard SD slots in laptops and cameras.
Is it compatible with Android phones?
Yes, most Android phones with a microSD slot accept it. Some devices require the card to be formatted before first use.
