The SanDisk Extreme microSDXC is a UHS-I card rated V30, U3 and Class 10, with quoted read speeds up to 190MB/s and write speeds up to 130MB/s. The A2 app performance rating targets Android phones, while V30 and U3 suit 4K video in action cameras, drones and dash cams. Against UHS-II cards it gives up peak speed, but most phones, action cams and drones only run UHS-I, so the extra bandwidth of pricier cards often goes unused. Buyers rate it 4.2 out of 5; the common complaints are cards that fail early or arrive slower than expected.
