Many storage devices and adapter boards look alike. When holding a module with a connector that looks suspiciously like the M.2, how do you know exactly what you are dealing with? Is that M.2 board a SATA drive, a fast NVMe device or a Wi-Fi/Bluetooth combo? Will a drive removed from an Apple computer work in a simple mechanical adapter, or will it require the original Apple device to access? A physical connector does not guarantee the underlying technology.
