Now you can hook up a dirt-cheap SATA disk drive to your PC or Mac by simply plugging it into this USB desktop adapter that works just like an iPod dock. Until now, if you wanted to add a bare hard drive to your computer, you either had to put it in some sort of enclosure, or open up the hood of your PC and install it next to the other drive in there. That's not easy for the uninitiated.
