I’ve bought two hard disks one is from seagate which is having 1Tb storage and the other is Sony having storage of 2Tb.I compared both and I felt seagate is better at its price but you can’t feel satisfied with its speed in copying files.Yes its very irritating unless you are having so much patience like budha.Then I used to put always in the usb 3.0 portal for faster transmission but Sony is better meanwhile transmission if you want your money spend on something to get complete satisfaction: )
