Query: Good Product

I am using it for storing photos, eBooks etc. I do not use it day-to-day basis. It is light weight, read/write is quite fast. Nice product. I am quite satisfied with this. It provides 2 USB cables. One for Data+Power another for Power only. The second one can be used if the power drawn through the first cable is insufficient. I don't need the second one. First one is sufficient for my IBM-ThinkPad.Two of the reasons I choose this product; it does not require a separate power source and it is light weight.
