Tripp Lite's USB 2.0/eSATA Hard Drive Dock gives you a quick and easy way to set up an external hard drive storage system. Plug the docking station into an available USB port on your computer or eSATA port, and pop in a 2.5" or 3.5" SATA drive for an instant external storage device. Far easier than installing the hard drive internally or in a caddy, the USB/SATA Dock is easy to use, convenient and practical. Compatible with Windows 2000/XP/Vista/Win7. Includes 100-240V AC Adapter, 4-ft. USB 2.0 A-B cable, 7-pin eSATA cable. No disk drives are included with this unit. Tripp Lite Limited One Year Warranty.
