Western Digital My Book Mirror Edition 2TB USB 2.0 (WDH2U20000N)

I like it a lot! Sets up easily and I have it set to give me two 1TB partitions--one backing up the other. (I could also set it up as a straight 2TB storage drive.) Right now, I prefer the automatic backup. And, both partitions are independent--if one fails, the other isn't affected. Love it! (I also use other external hard drives for works in progress--then move the final product to this unit.) Another plus is that this unit goes to sleep when my computer isn't on. I had another, older, unit that had to be disconnected from power even when the computer was off, otherwise it got too hot. The automatic power-down protects this unit from overheating, which is cool (sorry).Buy Western Digital My Book Mirror Edition 2TB USB 2.0 (WDH2U20000N)!
