ProGrade Digital has developed its new CFexpress Type B 4.0 Iridium 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 cinema cameras. Available in 400GB, 800GB, and 1.6TB capacity and performance levels provide read speeds up to 35500MB/s CFexpress Type B cards are ideal for quickly off-loading high volumes of video or RAW photos and sustained write speeds up to 850MB/s and 1500MB/s respectively perfect for uninterrupted, cinematic capture of RAW 4K or 6K video. The CFexpress Type B Iridium cards are VPG400 rated.

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.
