Designed for microSD devices such as smartphones, drones, and action cameras that can capture Full HD and 4K video, as well as raw and burst photography, the 512GB Extreme UHS-I microSDXC Memory Card from SanDisk has a capacity of 512GB, is compatible with the UHS-I bus, and features a speed class rating of V30, which guarantees minimum write speeds of 30 MB/s. If your device does not support the V30 standard, this card also supports the U3 standard, which also guarantees minimum write speeds of 30 MB/s. Read speeds are supported up to 245 MB/s, and write speeds max out at 170 MB/s. Aside from support for UHS-I, V30, and U3, SanDisk also built this card with support for the Application Performance Class 2 (A2) spec, which includes optimizations to give Android users an improved mobile experience, delivering faster mobile app performance. The A2 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, such as audio, graphics, saved profiles, and in-app permissions. As with most SanDisk media, this memory card is shockproof, x-ray proof, and waterproof, while also being able to withstand temperature extremes. Additionally, SanDisk's Memory Zone app offers users a simple way to organize, browse, and back up files on their Android mobile device.
