ProGrade Digital has developed its new CFexpress Type B 4.0 Gold class memory cards with next-generation performance leveraging PCIe Gen 4 interconnect with NVMe host controller interface for use in future Mirrorless, DSLR and high-definition video cameras. Available in a 240GB, 512GB, 1TB, and 2TB capacity and performance levels provide read speeds up to 3400MB/s CFexpress Type B cards are ideal for quickly off-loading high volumes of video or RAW photos and sustained write speeds of 700MB/s (240GB) 850MB/s (512GB) and 1500MB/s (1TB, and 2TB) respectively perfect for uninterrupted, cinematic capture of RAW 4K or 6K video.

NOTE: Current CFexpress cameras will not be able to take advantage of the maximum speed of this card. Until CFexpress 4.0 cameras are introduced, the benefit of this card is tripling the speed of your workflow when downloading content with the ProGrade Digital PG05.6 USB 4.0 Reader.
