Hardisk these days is like a backup of all your data which you need in future and if copying the backup is slow then it is of no use.Well buying hardisk is first of all you will check its design and weight which is good so I did buy it and after buying it I was hopless because you should have patience copying the data. And the service is also poor because there are less stores all around and sometimes I feel like throwing it because it is a waste of money spending 2000 bugs on to it and I will not suggest anyone to buy it.
