Hello friends, I use WD 1 TB Wired External Hard Disk from last 1 year and I didnt have any type of problem with this device. In my opinion this hard drive is very good because of some specific reasons, like- its size, its design, its speed & its quality. Its very good looking matte finish and small in size. So, too easy for carry one place to another as well as its speed is also very good and WD hard drive is fast respond than Samsung hard drive.
I personally recommended to all, who want to buy a hard disk. Go with WD
