ProGrade Digital COBALT 128GB UHS-II SD Card

The ProGrade Digital COBALT is built for professional photographers who need the absolute maximum speed from their SD cards. UHS-II with read speeds up to 250MB/s and write speeds up to 130MB/s — designed specifically for cameras with UHS-II slots like the Sony A1, Nikon Z9 and Canon EOS R5 Mark II.

GearFrame's Take

If your camera has a UHS-II slot, the COBALT is one of the best cards to put in it. ProGrade is a brand started by former SanDisk and Lexar engineers — the quality and consistency match the pedigree. Faster file transfers and better burst clearance justify the price premium for professionals.
