Compatibility
NVMe drives need an M.2 slot with a matching PCIe generation to hit their rated speed; SATA drives need a SATA header and cable.
A NAS's bay count sets the maximum number of drives, and each bay is sized for 3.5" or 2.5" drives (sometimes both). Drives are almost always sold separately from the NAS enclosure itself.
