At the 2008 CES, Thermaltake introduced a novel idea in the category of external storage, the hard drive dock. The BlacX dock supported either 2½" or 3½" SATA drives via a hot-swap, plug-in interface and featured USB 2.0 connectivity. It was an instant success. Although many other manufacturers would soon develop their own versions of the external drive dock, Thermaltake continued to refine their original design with subsequent models that added support for a 4-port USB hub, dual drives and finally eSATA. The item we have for review today represents the latest in the evolution of Thermaltake's drive dock, the BlacX 5G.
