FAQ
CFexpress is an upgraded version of the CFast 2.0 and XQD. The main difference being faster speed.
Formally, CFexpress is a removable media standard created by the CompactFlash Association (CFA) in September 2016. The further CFexpress 2.0 standard was announced in February 2019, which includes three form factors defined in the standard (Type A, B and C). All form factors leverage the PCIe Gen 3 interface and use established NVMe protocols to offer better efficiency, optimized power and performance for professional imaging and video markets. For more information please visit (https://compactflash.org/).
Any PRO version or Wise 512GB, 1TB and 2TB will support the necessary write speed for RAW or 4K 120P videos. Please download the compatibility chart HERE.
The PRO version media contains much more NAND Flash memories than the standard CFexpress Type B cards, even though the capacity on the label doesn’t show the full capacity. With a lower usable capacity, it allows us to access the full performance of the card.
Through customized commands and firmware algorithms, it optimizes both endurance and performance in line with native SLC NAND. 10x lifespan, and 3x faster compared to consumer TLC NAND products.
Certain cameras that use XQD cards can get a firmware update from their camera manufacturers to support CFexpress Type B cards (e.g. Nikon D5, D500, D850, Z 6 / Z 7 and Panasonic S1 / S1R etc.).
No, that would not be a wise choice, size matters (Type B: 29.6 x 38.5 x 3.8 mm / Type A: 20.0 x 28.0 x 2.8 mm).
At this moment only Sony, ProGrade Digital and Delkin Devices manufacture them.
