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.

CFexpress is a removable media standard created by the CompactFlash Association. There were three form factors defined in the standard: Type A, Type B, and Type C. All form factors leverage the PCIe® Gen 4 interface for higher performance based on a computing industry storage interface and utilize NVM Express™ 1.4c protocols.

What does VPG400 mean for the CFexpress Type B Iridium memory cards?

Video Performance Guarantee 400 (VPG400) means that when you are recording, you can ensure that the minimum write speed while recording is at least 400MP/s without dropping any frames.
