Using this product for last ten days continuously. It is running smoothly. For 1 TB, one will get 931 GB which is common. Speed varies on types of files, number of files, type of USB port using, System config etc. . For video file of size 2.02 gb , PC to HD speed avg 81 MBPS and from HD to PC avg speed 96 MBPS using USB 3.0 port. But what I disliked is its hardware part. It seems very fragile. See My pic how I kept my Hard disk for extra safety. One have to handle it very safely. Company trie...

Awesome product, have very good speed. As always on time delivery by flipkart. I'm very happy with it. and those who say speed not as listed just check for USB port it have lower speed for usb2.0 and high speed on usb3.0
