ProGrade Digital, a new memory card company founded by former Lexar Media and SanDisk employees, has launched a new line of speedy SD cards for high-resolution video recording and ultra-fast burst mode cameras.
The new cards meet the new V90 specification for SD cards with a sustained video recording rate of 90MB/s. The cards also feature a sustained read speed of up to 250MB/s and write speeds of 200MB/s for shooting and saving stills.
The ProGrade V90 cards will be sold in 64GB, 128GB and 256GB capacities for $100, $190 and $380, respectively.
According to ProGrade, the company performs component-level testing “down to individual memory chips” to ensure quality control. Their products come with a three-year warranty.
