One of the best at price, everything works perfectly.
USB 3.0 transfer rate is very good. Quality and build is perfect .
Metal body strong enough to withstand any normal drop but
the only con I found and it happens to me only that the cable and the port of the hard drive is slightly not that great I would say; because the cable sometimes feels like will breat at its metal edge and its not that sturdy .
Warranty and service by sony is great, accidentally I had an issue with it but they replaced it with a new one. So a happy customer.
Its been 4 years I have been using this.
cons.
Not repairable
