Pros Easy to set up and use. Good performance. A disk fault in raid 5 still allows access and will rebuild new drive in the background with good performance. Does not use more than 20 watts after boot up. Massive storage with 2 terabyte drives.
Cons Will take some time to check parity after each system boot, especially on raid 5 built with low priority. But parity check doesn't seem to affect performance badly. DLNA not supported.
Summary I have a older NAS 4000 which is faster, supports DLNA (can stream 1080p HD video to my TV, iPod and/or browser) as an independent unit on network. While the NAS 4000 is essential and fast (100 meg/s transfers), this unit shines with its near silence (you won?t hear it unless you lean close and listen), energy efficiency, massive storage (eight drives) and good performance (30 meg/s is acceptable for any application other than active database files) at a rock bottom price. Anyone who needs raid 5 to store multiple terabyte system drive backups, large numbers of HD video and audio files which are also stored in mobile device formats will quickly appreciate this unit. The security of raid 5, which continues to work even when one of four drives is unavailable, is a real relief. This unit brings a level of stability which allows you to comfortably reduce all those duplicate files spread all over the place.
