UHS Speed Class 10 Rated. The UHS Speed Class 10 rating lets theSanDisk SDXC 64GB Extreme PRO 200MB/s UHS-I U3 capture uninterrupted, cinema-quality 4K, 3D, and Full HD video at a minimum sustained write speed of 30 MB/s. If you’re shooting 4K video with a camera that uses the SD format, this is what you want.

Fast Read and Write. The 200MB/s read and 90MB/s write speeds allow you to transfer large amounts of data to and from the card with minimal bottleneck. It’s fast enough for most still photography uses short of extended continuous shooting. Its accelerated minimum sustained write speed prevents dropouts and stuttering, making it well-suited for 4K, 3D, and Full HD video recording.

Durable Construction. Like most SanDisk cards, the 64GB Extreme Pro 200MB/s is shockproof, X-ray proof, waterproof, and able to function in temperatures from -13 to 185°F, so you can use it in a broad range of environments, like snow, deserts, and pools.
