2.5” to 3.5” SATA Aluminum Hard Drive Adapter Enclosure with SSD / HDD Height up to 12.5mm


The 25SAT35HDD 2.5" to 3.5" hard drive adapter enclosure turns a 2.5" SATA hard drive (HDD) or solid state drive (SSD) into a 3.5" drive.

The adapter enclosure lets you substitute a 3.5" hard drive for a 2.5" SSD/HDD 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.

With support for drives up to 12.5mm in height, and high-capacity SATA I/II/III drives (tested up to 1TB) this HDD adapter ensures compatibility with virtually any 2.5" SATA hard drive or solid state drive.




  • Install a 2.5" SATA HDD/SSD into any 3.5" hard drive bay, such as a desktop chassis, backplane kit, or docking station
  • Replace your 3.5" hard drives with same-size SSDs
  • Repurpose unused laptop hard drives to work with your desktop computer, or as a hot-swap storage solution
