2.5-inch SSD/Hard Drive to 3.5-inch Bay Plastic Tray Mount Adapter Kit
This single piece mounting kit is much easier to mount the 2 solid state drives than the 2 piece metal bracket design. It's not recommend to mount 2 hard drives, because of heat issue. There are 4 screws holes on the underside of this unit for mounting the bottom drive. So unlike the 2 piece design, where you need to slide the brackets around to make the holes fit. The top drive mount using the screw holes on the side.Since the unit is just 1 solid piece, it also easier to mount into the computer's 3.5 inch bay.
