Summary: Three words - I Love It!. I populated this NAS with 4 WD Red 3TB drives for my 4 home PC network. It does everything and more what is advertised. It is easy to manage and to configure. With this unit on a UPS and "acres and acres" of storage, I expect this will last me a long time with confidence of my data being safe. This NAS being fully populated with 4 drives, it runs very cool and quiet.
Summary: I ended up being able to use this unit for its intended purpose once I upgraded to a multiseat quickbooks. but that is not the fault of this unit, that is a quickbooks issue. that being said, we use this everyday. it is a great unit. I am actually considering getting one for at home.
