The Thermaltake BlacX is a neat little USB-based hard drive docking station that fills a gap left vacant by removable hard drive racks and external hard drive enclosure systems. The small black box is free standing, but does require a DC power supply to function. It supports a single 3.5" SATA desktop or 2.5" SATA notebook hard drive at a time. Data is transferred to the computer via a 480Mbps USB 2.0 cable included in the package.
