Best Bargain Review - Western Digital WD Elements 1.5 TB USB 2.0 External Hard Drive
I purchased the 1tb Elements (WDBAAU0010HBK-NESN) for use with a Dish DVR 622.
Installation was was truly "plug and play". I simply took it out of the box, plugged it in, and it was immediately recognized by the DVR. I have since transferred about 200gb of content to/from it, and have watched content directly from the drive. So far, it is working perfectly. It automatically spins down after a few minutes of non-use, as well as when the DVR is powered off. It also spins back up automatically (less than 10 seconds) when the DVR accesses it.
One thing some people might not like: The case is designed to sit flat (as pictured), not on its side. There are four small non-skid pads on the bottom corners, but none on either side. There is no indication on the box, in the documentation, or on Western Digital's web site as to whether the drive will work properly on edge. As a general rule, WD drives are designed to operate sideways or even upside down (any X,Y,Z orientation), so this one probably will too -- but you'll need to provide your own non-skid pads.
