I have bought DELL 2TB External Hard Disk Drive in online. I am using this for my PC back up since two years and the processing speed is awesome and the device is not heating up or other issues. Its very compatible and portable, I am using this in my Smart TV. The internal segate installs enable default software while using first time and that was so good to organize our back up, very user friendly. I suggest people to go for Dell HDD without any oscillation.
