Before deploying M.2 SSDs, determine the type of socket on the host and check the module connector keying, as each connector should be inserted only in the appropriate socket. ATP M.2 SATA SSDs are B+M-keyed (can fit in sockets for B-keyed and M-keyed modules), while M.2 NVMe SSDs for PCIe 3.0 x4 lane are M-keyed.
