Have three pieces in use - from the first part now for more than 24 months in operation. Are mainly used with us as data / backup server. Configuration I find easy, many ways to configure On / Off Times and Spin On times, ACLs, and more. Of course we must make sure that you have the right plates purely doing [....], otherwise there are no nasty surprises - but that has nothing to do with the part - but with the operation: in my Dieseler I also do not use gasoline purely ... So no Green WD please! Otherwise: reliable, quiet (yes sounds come mainly from the plates themselves) and equipped with many connections (USB disk to UPS about printers, etc). Purchase I have definitely not regret it!
