UHS Speed Class 3 Rated. The UHS Speed Class 3 rating lets the SanDisk SDXC 1TB Extreme PRO 250 MB/s UHS-1 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 250 MB/s read and 170 MB/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.

Very High Capacity. At 1TB, this SDXC memory card enables uninterrupted continuous video recording at high data rates.

Durable Construction. Like most SanDisk cards, the 1TB Extreme PRO 250 MB/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.

Please Note. Just because this card is 1TB in size doesn’t mean you should fill it up without a backup. It’s best to not put all of your eggs in one basket!
