I buy this product on the 21 July 2017 from the ebay.com on rupees 8000. The data transfer rate from the hard disk to the computer is 15 Mbps on USB 2.0 and the 35 Mbps in USB 3.0. The data transfer rate from Computer to the hard disk is the 10 Mbps in USB 2.0 and the 18 Mbps in USB 3.0.
The other thing is hard disk is not providing that much speed while copying the date. This is less than the quality has a concern. The price of the hard disk is extremely high if I compare it to the sony hard disk or the WD hard disk.
The style and the design of the hard disk are good. But the size of this hard disk is bigger than the Sony hard disk and have more weight than the sony hard disk. So, not prefer this Seagate Plus Slim 1TB Wired external hard disk rather than this refer to the Sony hard disk.
