This high quality Removable SATA Hard Drive Drawer delivers a professional-grade SATA hot-swap solution, allowing you to quickly swap Serial ATA hard drives in and out of a computer without having to open the computer case. Simply install the (included) drive bay into a 5.25 inch drive bay on the host computer, then mount a 3.5 inch SATA HDD in the (removable) caddy. Connecting the SATA hard drive to the computer is as easy as inserting the caddy into the drive bay, which can be locked to prevent unauthorized removal of the installed SATA drive. A practical, time-saving hot swap solution, the drive drawer includes Swap Manager utility software that lets users swap drives in and out of the host computer without powering down the computer. A suitable solution for large volume drives, the HDD drawer supports SATA I (SATA/150) and SATA II (SATA/300) hard drives with a capacity of up to 1.5TB, allowing you to swap in large amounts of data in a matter of seconds. The drive caddy features two front panel ball bearing fans that help keep the enclosed drive cool, in turn helping to optimize operation while preserving drive lifespan. To prevent damage to the hard drive(s) while being transferred in and out of the computer, the drive caddy features shock absorbers and rubber cushioning that help limit vibration/shock to the drive. A dependable, long-lasting storage solution, the drive drawer features highly durable aluminium construction, with a 25K insertion rating and is backed by StarTech.com's 1 year warranty. This product is interchangeable as a replacement for StorCase SATA models S21J111, SC21J111 and RJR110.
