Summary: This is one of the most affordable arrays with RAID 5 capability and is very quiet. Be aware that if it is formatted as RAID 5 the capacity drops to just over 4 gigs because there are only 4 drives in the array. I had a data corruption issue which mimicked the failure of 2 drives and forced me to reformat the array and lose a lot of data. Tech support was very helpful but hard to reach- the did not answer their phone and took a day to answer email.
Pros: Attractive Design, Compact, Good value, Quiet, RAID protection
