ProGrade Digital UHS-II SDXC – 64GB (V90)
UHS-II / V90 • Up to 300 MB/s read • Up to 250 MB/s write • Min sustained 90 MB/s • 6K/5K/4K ready
Overview
The ProGrade Digital 64GB UHS-II SDXC (V90) card is built for cameras that generate rich data streams—think 6K/5K/4K/UHD video and rapid-fire RAW bursts. Leveraging the UHS-II bus, it reaches up to 300 MB/s read and 250 MB/s write, while the V90 rating guarantees a minimum sustained write of 90 MB/s to keep high-bitrate footage recording without dropped frames. Ruggedized for the field, it’s shockproof, X-ray proof, and operates across extreme temperatures, with a built-in write-protect switch for added safety.
While optimized for UHS-II/V90 bodies, it’s backward compatible with devices that support lower speed classes and buses (e.g., V60/V30 or UHS-I/U3/U1/Class 10), defaulting to the host device’s capabilities.

Compatibility (as provided)
Works with DSLRs, mirrorless, camcorders, and digital cinema cameras supporting UHS-II/V90. Backward compatible with devices that support lower speed classes/bus modes (performance defaults to host device specs).
Ideal For
High-resolution video capture (6K/5K/4K), high bit rate codecs, cinematic productions, and photographers shooting RAW bursts.
Pro Notes
- For uninterrupted video, rely on the V90 minimum sustained write of 90 MB/s.
- Use UHS-II readers to realize full transfer speeds; UHS-I readers will bottleneck.
- Enable the write-protect switch when archiving cards to avoid accidental deletion.
