Now, you don't even need to open your computer case or involve a drive enclosure to install a SATA hard drive! Supporting SATA (SATA 150) and SATA II (SATA 300) 3.5" and 2.5" notebook hard drives, this innovative device allows you to simply "plug" the drive into the dock which connects to the host computer using an available USB 2.0 connection, instead of having to connect or enclose the drive. A perfect solution for data recovery, drive imaging, and testing centers, or any environment that requires fast access to uninstalled/archived drives, SATHDDDOCKU2 supports plug and play installation on most operating systems, and provides data transfer speeds of up to 480Mbps (using USB 2.0) between host and dock - ensuring effortless data dumps/backups and hassle-free file transfers.
