vs NVMe: What is the difference when it comes to SSDs? m 2 slot vs pcie 2 SATA True dual PCIe cards have x8 connector, for example AOC-SLG3-2M2 To fully use it, you need an option in bios to split x8 link into m2 expansion slot When selecting a PCIe SSD, you should also consider transfer speed PCIe has a data transfer rate of 16 GTs, however, PCIe has 8 GTs

m2 expansion slot 2 drives are “keyed” at one end so as to prevent the end-user from inserting them in an incompatible socket PCIe NVMe drives are 'M' keyed SATA ones,

m2 slot mainboard 2 SSDs use the port and are cheaper because they don't need an adaptor or a board designed to fit in the PCI slot They both use 4x PCI is a slot that can interface with SATA , PCI Express
