SANDISK Extreme PRO SDXC 64GB 200MB/s V30

Designed for SD devices that can capture Full HD, 3D, and 4K video, as well as raw and burst photography, the SanDisk 64GB SDXC Extreme PRO UHS-I Memory Card has a capacity of 64GB and is compatible with the UHS-I bus, and features a speed class rating of V30, which guarantees minimum write speeds of 30MB/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 200 MB/s and write speeds are supported at a maximum of 90 MB/s. A built-in write-protect switch helps protect against accidental erasure of card data.
