ProGrade Digital 320GB CFast 2.0 550MB/s Cobalt Memory Card 2 Pack

ProGrade's CFast™ 2.0 memory cards guarantee sustained read and write speeds up to 550MB/s and 470MB/s respectively. These cards are Video Performance Grade 130 (VPG 130), ensuring a minimum write speed of 130MB/s within the camera, meeting the standards required by high-performance cameras like the Canon™ Cinema EOS line and Canon EOS 5D Mark IV when creating in Motion JPEG.

ProGrade Digital CFast cards are also compatible with Cinema cameras from Blackmagic Design and RED Digital, allowing precise capture without dropping frames when creating 8K, 6K, 4K, Full HD and high bit rate RAW and MPEG-4 files. Fast action and sports photographers will achieve maximum performance from their cameras when working in continuous-burst mode, thanks to a ProGrade Digital CFast Cobalt burst write speed of up to 520MB/second. Whether in the field or studio, creators will dramatically reduce the time spent moving files from memory cards to workstations, backup drives, or field recorders, courtesy of a sustained read speed of up to 550MB/second.

Refresh Pro compatibility allows professionals to ensure that their cards are always optimized for maximum performance and also allows periodic monitoring of card health – critical to ensuring trouble-free operation in advance of critical shoots.*
