ProGrade Digital has introduced a 512GB version of its Cobalt UHS-II SDXC memory card, which - like previous SD V90 Cobalt memory cards with capacities of 64GB, 128GB and 256GB - offers maximum read speeds of up to 300MB/s and write speeds of up to 250MB/s.
The ProGrade Digital SDXC UHS-II, U3, Class 10, V90 cards target professional use in digital cinema cameras, high-end DSLRs and mirrorless cameras whose recording formats such as RAW 8K, 6K, 5K, 4K and UHD produce very large data streams and thus also require higher capacities of the memory card used. According to the V90 standard, a minimum sequential write speed of 90 MB/s is guaranteed for recording, for example, 8K video files at 60/120 fps.
The new card is also compatible with ProGrade Digital&s Refresh Pro software, which allows professional users to restore their ProGrade Digital cards to factory condition and monitor the health of their cards. In addition, the Prograde Digital SDXC UHS-II V90 512GB memory card has built-in error correction that detects and corrects data write and data transfer errors.
