CFX-B and CFX-B PRO series CFexpress media enable rich dynamic range of 8K RAW*4 continuous shooting and video recording for future premium DSLR, mirrorless and video cameras like a walk in the park. With the design of PCIe Gen 3 x2 interface, the cards provide blazing speeds, over 3 times faster than the best CFast 2.0 and XQD form factor.
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.

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.
Only 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.).
You can try, but that wouldn't be wise. Size matters (Type B: 29.6 x 38.5 x 3.8 mm / Type A: 20.0 x 28.0 x 2.8 mm).
