For a "1TB" NAS, a typical RAID 1, RAID 5 + Spare or RAID 10 configuration is going to yield only somewhat less than 500MB of usable storage. Given its high price, the Ethernet Disk RAID probably isn’t targeted at the home market. So I didn’t find the lack of web and UPnP AV servers and download clients particularly disturbing. That’s a lot of money for the number of usable gigabytes, but fault tolerance comes at a (high) price. And in a small business environment, data availability is a key consideration.
I was disappointed by some of the small issues encountered, such as email notification not working properly, lack of FTP session logging, the inability to update the SSL security certificate, and lack of administrator session timeout. But those shortcomings wouldn’t be enough to keep me from considering the Ethernet Disk RAID for an SMB environment.
