Designed for a wide range of still and moving image capture applications, the 640GB CFast 2.0 Cobalt Memory Card from ProGrade Digital provides read speeds of up to 550 MB/s, burst write speeds of up to 520 MB/s, and sustained write speeds of up to 470 MB/s, all of which help to facilitate quick data transfers. Additionally, the Cobalt's minimum write speed is guaranteed not to drop below 130 MB/s. This card is resistant to temperature extremes, shock, and X-rays, and uses error correction and wear-leveling to detect and repair data errors and maintain a longer operational life.

This card is also Refresh Pro ready, which uses ProGrade Digital's Refresh Pro software and a ProGrade Digital card reader to monitor card health and restore the card back to factory conditions. Furthermore, a laser-etched, unique serial number on each card allows for quick compatibility checks and after-sales support.
