I'm really impress with the NSS322.. I have never seen a NAS box with so many features. The box was very easy to setup and configure. It benefits small businesses like ours as a network storage server with some multimedia capabilities. The multimedia function although needs some tweaking if it wants to target customers that demands rich multimedia features. Also, sometimes it plays music files and sometimes it doesn't.. maybe it's missing certain codecs? On the good side, disk managing was straight forward. It was a piece of cake to RAID the two disk together and the reporting function like SMART gives us good indications about the status of the disk. Encryption of the file system is also a nice feature if you plan to store secret files!
One enhancement request from my side is authenticating from other type of LDAP servers besides Microsoft Active Directory... You can't forget the LOTUS and Linux people!
