Sony has said it is developing CFexpress Type B memory card with data retrieval speeds of up to 1,700 MByte/s, similar to mid-range and high-end SSD models. This series of memory card uses the same slot as the XQD standard which is currently popular on Sony dedicated camcorders or Nikon cameras.
CFexpress Type B memory cards are 3 times faster than the company’s CFast 2.0 (read speed 530 MByte/s). With a data writing speed of up to 1,480 MByte/s, the card targets devices that require high-speed data write at bitrate, which can reach more than 11,840 Mbps. CFexpress uses the PCIe Gen3 protocol proposed by the CompactFlash Association.
With the TOUGH logo, the memory card is certified with high durability with the ability to withstand bending forces of 70N, bearing 5 times from the height of 5 meters. The card is also resistant to high temperatures, anti-X-rays, anti-static or ultraviolet rays, durable in harsh environments.
In the future, some models such as the Nikon Z6 and Nikon Z7 will receive new firmware updates to support CFexpress memory cards. Because of using the same pins with the XQD, manufacturers only need to adjust the firmware so that the devices can use the new card standard.
Sony also released a dedicated MRW-G1 CFexpress card reader for this memory card to optimize data access to the computer.
Currently, Sony is ready to release a 128GB memory card. In the future, the company will issue additional capacity of 256GB and 512GB. With more and more high quality data being created, CFexpress promises to be a suitable memory card for specialized camera and camcorder equipment.
