CFX4-B and CFX4-B PRO series CFexpress media enable rich dynamic range of 8K RAW continuous shooting for high-end DSLR, mirrorless and video cameras like a walk in the park. Operated in PCIe Gen 4 x2 interface, the cards provide blazing speeds more than 6 times faster than the best XQD memory media.

DESIGNED BY PROFESSIONALS, FOR PROFESSIONALS

We know the strenuous demands required for working professionals in the field. We got you covered.

MAX SPEEDS OF UP TO 3700 MB/S READ
AND 3600 MB/S WRITE

Burst speed for read and write are more than 6 times faster than the best XQD media, leveraging the maximum performance of the camera.

BUILT FOR 8K PRO PHOTO & VIDEO

Captures detailed, high-definition frames without drop off in performance as the capacity gets used by steady sustained write speed.

NON-STOP RECORDING TIME

The large capacities up to 4TB provide ample space for RAW footage. Creators are able to store more content non-stop in harsh and unforgiving environments.

ULTIMATE DURABILITY

Wise CFexpress Type B cards are protected against moisture, dust, X-ray, magnets and shock.

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/).

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.

Depend on usages.

For single and sometimes continuous shooting or people who are looking for cost-efficient solutions, our standard blue version is more than enough.

For high-speed continuous shooting all the time like railroad, animal or sports and heavy movie recording, the PRO media is at your service.

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).
