Capture cinema-quality 8K video and high-res images with up to 300MB/s read and write speeds, V90 sustained performance, IP68 protection, and 64GB capacity
Capacity 64GB
The SanDisk Extreme PRO is a 64GB full-size SDXC memory card built for professional cameras and video gear. It uses the UHS-II interface and carries a V90 video speed class rating. Sustained write performance reaches 90MB/s on compatible devices while peak read and write speeds both hit 300MB/s. The card is IP68 rated for water and dust resistance and tested to survive 19.6-foot drops.
This card suits photographers and videographers who record 8K footage at 30 fps or 4K UHD at 60 fps and need buffer-clearing write speeds up to 300MB/s. It also fits workflows that benefit from 300MB/s transfer rates during post-production. Buyers who need more than 64GB of capacity for longer shoots without swapping media should look at higher-capacity options. Users whose equipment only supports UHS-I or lower speed classes will not gain the rated performance.
The single specification that determines whether this is the right part is the V90 rating, which guarantees a minimum sustained write speed of 90MB/s. If your camera requires V90 for 8K or high-bitrate 4K recording, this card meets that requirement. If your device only demands V60, V30 or a lower class, the V90 capability exceeds what is needed.

Other versions of this model
The card guarantees a sustained minimum write speed of 90MB/s on V90-capable devices, which is required for cinema-quality 8K video recording.
Yes, the SDXC UHS-II card is backward compatible with UHS-I slots, though read and write speeds will be limited to the older interface's maximum.
Use a UHS-II card reader and benchmark tool to confirm sequential read and write speeds approaching 300MB/s, and check that 8K video at 30 fps records without dropped frames.
