The SanDisk Extreme microSDXC is a 512GB UHS-I card rated A2, V30, U3 and Class 10, with read speeds up to 190 MB/s and write speeds up to 130 MB/s. It is built for phones, drones and action cameras that record 4K video and burst or raw photos, and it is rated water, shock and X-ray proof. The A2 rating helps app performance on Android phones, and the V30 write floor of 30 MB/s keeps 4K recording steady. It sits above basic cards on speed and durability, but it is still UHS-I, so devices that use UHS-II or the newer UHS-I DDR200 mode will not reach the full read speed.

Owners of the Extreme line generally report reliable 4K recording and fast transfers, and the A2 rating is noticed on Android phones. Complaints center on real-world write speeds falling short of the headline figure and on cards that slow down or fail after heavy use.
