I have bought this harddisk almost 4 years ago.
It is the best hd I have ever used. I have use it to its max capacity. I am not facing any issue in my till day use. After installing the software came along with the hd you can get 70-80 mbps speed in usb 3.0 port. The usable space is 931 GB. Build material is good. Campatible with all version of windows. For better speed don't forget to update firmware of wd harddisk
