This WD harddisk is best.After using lot of hardisks I came across this WD.The best about this harddisk is the speed of transfer(80to90mb/ps).So you easily transfer a lot of files within minutes.It is small compared to other hard drives and it looks so beautiful.It also comes in warranty.It doesnot corrupts which is best.I have find that other hard drive gets easily damaged but WD hard drive is great.
