2.5" Solid State Drives (SSDs) or Hard Disk Drives offer many benefits over larger 3.5" hard disk drives, such as lower heat output, faster speed (with SSD), and lower power consumption. But installing a new 2.5" SSD or HDD into an existing computer may not be possible due to lack of 2.5" bay drive support. The SABRENT 3.5" to 2.5" Bay Drive Converter Kit easily transforms any available 3.5" bay drive to accommodate up to two 2.5" hard disk drives or SSDs. The Converter Kit is designed to work with all types of computer cases (screw on type or tool less type), and can be installed quickly. The adapter is constructed from robust SECC steel to ensure strength and integrity of the adapter. Designed to connect motherboards and host controllers to internal Serial ATA hard drives and DVD drives, quickly upgrading your computer for expanded storage. PLEASE NOTE: This cable does not provide power. It is a data cable only. Drive needs to be powered separately.

This 3 Pack of 20" cables is perfect for your next computer setup or to have handy as reliable spare part for last minute setups and troubleshooting. Backward Compatible with SATA I & II.
