Casing for 512GB M.2 PCIe SSD

This is an M-key-only drive, so it's not as easy as if it were a B+M drive.  However, the adapter below may do the job in a more roundabout way.

Install the SSD onto the "M key" area of the adapter, then install the adapter into an available PCI Express card in a motherboard.  It should appear as a standard drive.

oh that means we have to use a desktop to copy out the data... so not that straight forward as able to connect as external usb drive

That's correct.  There are USB converters available for B+M interfaced drives, but this particular one is M interface only.

can show a link to how to see the differences between  M and B+M interfaced drives ?

Note the different slot locations on the edge connectors.

"The M interface provides x4 PCIe, SATA, and SMBus."  But not USB.

Had bought the adapter pCi express card.. is it possible to assemble this in any of the pci express slots? (Attached the motherboard design)
