Ars Technica provides a 6 page review of the Synology DS-412+, focusing on features, software, and pretty much everything you’d want to know about any NAS.
Other contenders in the home NAS space include QNAP, NetGear, and Iomega, but I went with Synology chiefly due to their reputation for performance. The DroboFS was the very definition of “easy to use,” but after more than a year the slow read and write speeds just became too much. After scouring forums and reviews to find a replacement, I kept coming back to the then-newly released DS-412+.
