CFexpress is a standard for removable media cards proposed by the CompactFlash Association (CFA). The standard uses the NVM Express protocol over a PCIe 3.0 interface with 1 to 4 lanes where 1 GB/s data can be provided per lane. There are multiple form factors that feature different PCIe lane counts.[1] One of the goals is to unify the ecosystem of removable storage by being compatible with standards already widely adopted, such as PCIe and NVMe. There already is a wide range of controllers, software and devices that use these standards, accelerating adoption.
