The M.2 to 2.5" SATA III Adapter from Sabrent allows M.2 SSDs to be used in 2.5" SATA drive bays. The adapter fits one M.2 NGFF SSD and connects to your host system using its SATA III 6 Gb/s interface. A pass-through design also allows this adapter to be used externally, via a separately sold USB to SATA cable. Built using aluminum, this adapter helps protect against drops, shock, and dust. To help get you up and running and make installation into a 2.5" drive bay more user-friendly, screws are included.
