Additionally, Cobalt's minimum writes 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.
