Previous speakers have already described the vulnerability of this disk: - The silicone coating is attached and does not stick - The USB 3.0 port is not firmly connected to the housing and moves with plugged USB 3.0 connection cable, a platinum damage could result However, there are advantages to which I would like to note: - The hard disk has a very low power consumption and connects easily to any USB 2.0 port (without Y cable) operate - Despite the described vulnerabilities it considers the toughest working conditions and runs itself in a bag with water frozen after thawing again - Usual 1TB disk often fall after a year of operation of - of this type is not a single case known to me - The running noises are almost inaudible, the plate is in continuous operation lukewarm at best, positive for life - The connection cable is always on board Conclusion: I have great confidence in this hard drive for backup purposes, it is ideal. For me, clearly the no. 1 - real alternatives in this price range do not exist.
