Hi friends I just baught this hard disk WD My Passport Ultra 1 TB.It is actully small and lightweight as passport. Easily fits into your pocket which is really nice. Build quality is also very good. Easy to install easily detected in my pc and laptop. Works with MAC also but requires formatting.It comes with software for backup and some security software.This Hard Disk supports both USB 2.0 and 3.0, give good speed with 3.0(I got 60 to 70 mb/s) and with 2.0(30 to 40 mb/s) I was expecting more better performance. I like its build and size, it looks good and overall its a good product at this price.
