Here is the 5 bay version
of the one I have. I am not trying to act as a shill for Netgear, but I had another brand that worked just fine with my NV+, but when I went to the NVX (32 bit x86) it would not allow the NVX to connect properly, so I had to replace it. I went all Netgear and got the GS108 and have not had any problems since. If you are in the U.S., this is a hard price to beat. In fact, I'm thinking of getting one of these for when I want to expand my network.
Remember - the NAS is not a backup plan.
Backup = Good, No Backup = Bad
