2.5" Solid State Drives (SSDs) or Hard Disk Drives offer many benefits over the 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. Thermaltake 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 (both screw-on type or tool-less type, and can be installed within a minute. Constructed from robust SECC steel to ensure strength and integrity of the adapter.
