Like others have said, this drive is not very fast. The big problem with it is that it is heavy. I used this to back up VERY important data, and since I manage International business, sometimes I can be on the road for weeks at a time. Therefore, I live or die by my hard drive. This thing fell off a chair to the floor, maybe 18 inches and died. It is only a few months old! What a disappointment, and I lost months of work. I know IT people...3 back-ups on two different types of media. Easier said than done.
