I brought adata hd710 1TB for rupees 4200 in a offer.
The build quality is not what I expected but it is still ok.
One important thing is that the port of this hard drive is not stable and it is somewhat loose.And they paste a rubber over the hard drive with some cheap adhesive.
Despite of all this in performance this drive really outshines.It gives 95MB/S of writing speed in USB 3.0 and fairly high read speed of 100MB/S.Although these numbers are less than which were mentioned in the box.But thats usually the case.
