I just bought this hard drive disk a week ago. This is little bulky and needs very good care to handle. Performance wise this hard disk drive is better when copying from hard drive to my computer and vice versa is pretty good. It gives me average of 100 MB/s of copying speed via USB 3.0 connection and average of 40 MB/s via USB 2.0 connection. I do not see any negative point till now, except being bulky. For now I would definitely recommend this to all. I can not say anything about service and support because I have not faced any difficulty till now.
