There are lots of company which produce external wired Hard Disk. But Seagate is my first reccomendation to anyone. I have a WD 1TB Hard Disk and my friend has Seagate 1TB Hard Disk. Several times I used it for my profession. And using it I am really happy with it.
Because its speed is really good and smooth transfer. Very minimum flactuation of speed. And I will personally order a new one. And the look and furnish is really awesome. I like red color from Seagate. Their service is also very good. No doubtly you can go for it.
