Tripp Lite's USB 3.0 SATA 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 3.0 port on your computer, then insert a 2.5" or 3.5" SATA drive for an instant external storage device. Transfer data at SuperSpeed USB 3.0 rates up to 5Gbps (provided computer is USB 3.0 capable). Far easier than installing the hard drive internally or in a caddy, the USB 3.0/SATA Dock is easy to use, convenient and practical. It is compatible with Windows 2000/XP/Vista/7/8, and backward compatible to older USB 2.0 and 1.1 computers (480Mbps and 12Mbps transfer speeds respectively). It also includes a 100-240V AC adapter and 4' USB 3.0 cable.
