The speed is just average i.e. 25-27mb/s. The best part of me is the brand sony and the warranty 3years from the date of purchase. That was really cool. Looks wise is not that attractive but simple and ok. I dont have much to say since my review was base of just one time of used. But I would recommend friends and people looking for 1Tb with ok price range to go for it. Tested for the writing speed, just amazing speed inUSB 3.0, performance is better.
