Our take on the SanDisk Ultra microSDXC Class 10 U1 A1 120MB/s 512GB + SD Adapter

The SanDisk Ultra microSDXC 512GB is a UHS-I card rated Class 10, U1 and A1, with read speeds up to 120MB/s and a full-size SD adapter in the box. It is built for Android phones and tablets, Nintendo Switch, dash cams and tablets that record Full HD rather than 4K. The A1 rating speeds up app launches and storage, and the 512GB capacity holds a large photo and video library. It sits below SanDisk's Extreme line, which adds V30 and U3 ratings for 4K video and sustained writes, so pick this one for everyday storage and the Extreme for cameras and action cams.

Is 512GB the largest size?
