The latest CFexpress memory card update 4.0 will double the speed to 4 GB/s while still being backward compatible: CompactFlash Association members: Additional information: CFexpress 4.0 delivers double the theoretical throughput of CFexpress 2.0 while maintaining the same form factor LOS GATOS, California – CompactFlash Association (CFA), the organization responsible for professional removable media specifications such as CompactFlash®, CFAST®, XQD®, and CFexpress® announces the release of the CFexpress 4.0 logical and physical specifications increasing the performance of the existing CFexpress 2.0 specifications while maintaining backward compatibility targeting the professional imaging and industrial markets requiring high-performance data capture and transfer. CFexpress 4.0 is an evolutionary specification riding on the great success of CFexpress 2.0 employing the industry standard PCI Express® (PCIe) Gen4 bus and NVM Express (NVMe) 1.4c logical interface for even higher performance and efficient NAND Flash access. With its three form factors, CFexpress 4.0 continues to support diverse performance levels to match various market requirements maintaining consistent electrical, logical, and physical interfaces while setting realistic power consumption targets for wider adoption of the CFexpress 4.0 for battery-powered applications in the imaging and industrial markets. Utilizing widely adopted open standards allow the use of established development platforms saving development time, cost, and effort. CFexpress was developed in 2016 with the charter to become a removable media standard that can span various vertical market segments providing a stable and future-proof platform with economies of scale. Since then, the standard has been widely adopted by the imaging and industrial market segments. Performance With the adoption of PCIe...
