The 2.5” to 3.5” SATA Aluminum Hard Drive Adapter Enclosure with Solid State Drive /Hard Drive Height up to 12.5mm turns a 2.5" SATA hard drive or solid state drive into a 3.5" drive. The adapter enclosure lets you substitute a 3.5" hard drive for a 2.5" drive in any application that would typically require a 3.5" drive, such as desktop chassis, backplane, or docking station. The enclosure has the same dimensions as a standard 3.5" hard drive, including mounting points, and SATA connector locations.
