M.2 drives with PCIe 4.0 4x interface

PCIe 4.0 4x

— connection according to PCIe standard version 4.0, providing 4 data transmission lanes.

Version 4.0 ensures data transfer speeds of nearly 2 GB/s per lane; thus, the 4 lanes provided in this variant deliver about 7.88 GB/s. Moreover, drives with this interface can be connected to earlier and/or slower versions of M.2/PCIe — the only limitation being that the operating speed will be restricted by the capabilities of the motherboard.
