Sandisk Extreme pro sdxc uhs-1 512gb 170mb/s

The SanDisk Extreme PRO UHS-I SDXC 512GB memory card has a capacity of 512GB, is compatible with the UHS-I bus, and features a V30 speed class, guaranteeing minimum write speeds of 30MB/s. The SanDisk 512GB is designed for SD devices capable of capturing Full HD, 3D, 4K video, and raw and burst photos. If your device does not support V30, this card also supports U3, which also guarantees minimum write speeds of 30MB/s. Read speeds are supported up to 170MB/s and maximum write speeds at 90MB/s. A built-in write-protect switch helps protect against accidental erasure of data from the card.
