I dont like this hard disk because it is very costly And the material used in this hard disk Is very worst.
this hard disk is compatible with both usb 3.0 and 2.0 But it gives speed only like as given by 2.0 And the hard disk is very very costly anybody can buy 2tb hard disk at the rupees of 7200/- from any other comoanies like transcend, dell, WD And also from some others.
this is only an okay product not very good and it also does not support restore and backup.
so I suggest you to dont buy this hard disk.
