I bought this hard disc 2 year ago it good in design shape but it should more slim its weight is good and data transfer rate is good but not excellent when you will connect to you laptop or desktop and trying to transfer data from wb to your lap or desktop is speed will be 30 mbps average. if you will use usb 3.0 then it speed only increase upto 37 - 40 mbps it is unexpected to me if you will use and coping application(like tera copy) then the speed could increase upto 50 55 mbps the writing speed is 12 15 or 20 mbps depending for file types.
so overall it very good hard disc for who have time. who does not have much time then it is not for you.
