Im vamshidhar living in Hyderabad, I bought toshiba canvio basics 1 tb portable hard drive ( black colour) 3 months back from paytm. It costed me around 3700rs. I am very happy with the product as its transfer speed is 5 Gbps which is good. It supports all windows os systems.
Its performance is good, it wont gets heated up because of load, it doesnt require any any ac adapter. Even the service centers are reliable with all the stuff. Its worth value for our money. Toshiba is even providing 24/7 helpdesk to its customers.
