A 512GB microSDXC card from SanDisk's Ultra line, rated Class 10, UHS-I U1, V10 and A1, with read speeds up to 100MB/s and a full-size SD adapter in the box. It is built for everyday storage: phone and tablet expansion, Nintendo Switch game libraries, dash cams, security cameras and 1080p video. The A1 rating means apps stored on it load reasonably well on Android, though it is not a high-endurance or U3 card. Rivals like the Extreme and Extreme Pro lines write faster and survive more rewrite cycles, but the Ultra is the value pick for capacity over speed.

Owners rate it highly for capacity and everyday reliability, especially in phones, Switches and security cameras. Complaints center on slower-than-expected write speeds and the occasional card failing or arriving counterfeit.
