Summary: The unit itself is relatively simple to set up. For a home user or corporate user who have IT personnel onsite, this is a reasonable system. That is until you need tech support. Mine had a drive fail inside of 30 days of putting it into use. I had already configured the unit, loaded Data and shipped it to a remote office across the country. Shortly after that the drive failed.
Summary: Worked very well until I needed to change one of the drives. NB A little slow when accessing via Mac due to AFP speeds. The ReadyNAS configuration was 2 x 3TB and 2 x 1TB all as one volume Raid 6. So I replaced a drive 3TB disc with confidence and waited 7hrs for it to rebuild. On completion I was informed that the drive was now made up of 2 volumes, 1 x 3TB which was Raid 1 and 2 x 1TB Raid 5 with the other old 3TB drive, not being used and all the data lost. Not great!
