Optimized to excel in smartphones, tablets, drones, action cameras, DSLR cameras, plus 4K and Full HD camcorders, the Superior Pro UHS-I microSDXC Memory Card from Silicon Power features a storage capacity of 256GB and takes advantage of the UHS-I bus for read speeds up to 100 MB/s and write speeds up to 80 MB/s. It also uses the V30 Video Speed Class rating, which guarantees minimum write speeds of at least 30 MB/s. All of this allows you to capture 4K and Full HD video, raw and JPEG photos, and rapid shutter bursts.

Aside from support for UHS-I, V30, and U3, Silicon Power also built this card with support for the Application Performance Class 1 (A1) spec, which includes optimizations to give Android users an improved mobile experience, delivering faster mobile app performance. The A1 spec allows the card to manage random read input-output access per second (IOPS) operations so it can quickly open apps and process accompanying tasks, including audio, graphics, saved profiles, and in-app permissions.
