Designed for use in devices that support the UHS-I bus, such as digital cameras, DSLRs, camcorders, and more, the 64GB 300S UHS-I SDXC Memory Card from Transcend can capture Full HD video, plus raw and JPEG still images. It has a capacity of 64GB and features a speed class rating of U1 / Class 10, which guarantees minimum write speeds of 10 MB/s. Read speeds are supported up to 100 MB/s and write speeds max out at 20 MB/s. A built-in write-protect switch helps to safeguard against the accidental erasure of card data.
