Decent cheap NAS. Dual bay and Gigabit NIC.
Older reviews are often not great as early firmware was a little poor and restrictive. Newer firmware has fixed the bugs and relaxed the 3 user limitation. No it's not a ReadyNAS but neither is the price.
Mine streams media fine to my XBMC Revo, Xbox360, PS3 and Android phone with no issues.
includes DLNA, Printserver, Bitorrent client , Windows/MAC backup, FTP Server and iTunes library support
