Wise explains the new CFexpress 4.0 Standard

CFexpress 4.0 delivers double the theoretical throughput of CFexpress 2.0
while maintaining the same form factors. The CompactFlash Association (CFA), the organization responsible for professional removable media specifications recently announced CFexpress 4.0 and I caught up with Wise to find out more about it.

CFexpress 4.0 doubles the performance of the existing CFexpress 2.0 specifications while maintaining backward compatibility. CFexpress 4.0 utilizes industry-standard PCI Express (PCIe) Gen4 bus and NVM Express (NVMe) 1.4c logical interface for even higher performance and efficient NAND Flash access.

CFexpress was developed way back in 2016, and since then, the standard has been widely adopted by the imaging and industrial market segments.
