Hard drive docks can come in handy in several instances: home or office data transfer, back-up files or switching hard drives, or even at the LAN scene. Most models' convenience ends with one external and one internal hard drive. Imagine, however, the possibilities if you could have two docks in one, allowing for data transfer from not only an external to internal, but external to external, and being able to read and write two hard drives simultaneously. Even more impressive would be if both docks supported 2.5" and 3.5" hard drives. Thermaltake had those very ideas in mind when designing the BlacX Duet, and has sent us the end product to try for ourselves.
