I bought it recently and it looked really good but things changed within a blink of an eye. The hard disk crashed after a week and that too without using it. I used it for transfer of 10 15 movies and in the middle if it crashed. The data transfer speed is 20 Mbps at Max and that too for contiguous files like movies.
The speed will drop to kB in case of discrete files, typically found in games or application softwares. Final word don’t buy it at any cost. The service centre will take atleast 3 weeks to replace if its warranty period. Not at all happy.
