One of the side effects of continually increasing your computer storage space is that you can end up with a pile of spare hard drives. If you don’t have another computer to put them into, Thermaltake offers an interesting solution, the BlacX Duet storage controller, at a suggested retail price of $69.99.
The BlacX Duet allows you to drop one or two hard drives into the controller. When attached to a computer, each drive appears as an additional local drive. You can easily remove either of the drives and insert another drive from your collection of spares.
