Summary: had a hard time negotiating a gigabit network connection and I tried connecting it to various gigabit switches; the only way to make it connect at 1Gb was with a cross over cable directly to a computer, then manually forcing the configuration to 1Gb; the transfer rates don't really reflect 1Gb...
Works great only with Firmware 1.02. Do not upgrade to 1.03.

Summary: I have owned the DNS-321 for a couple of years now and it works very well as a relatively inexpensive RAID solution for my home. The only frustrating set-up problem is the inability to format disks and set-up as RAID configuration using firmware 1.03.
Summary: I agree with S. Kosto. There is a Linux kernel bug in the software that runs the DNS-321. This means that my backups are not guaranteed to be accurate in a very small number of files. I addressed the above issue by buying a 3rd HD and an external USB enclosure.
Summary: I bought one of these several months ago and installed on my home network. For me, the unit does exactly what I wanted it to do, but there are many advertised features THAT DO NOT WORK AS DESCRIBED...IF AT ALL.
Summary: I've had my DNS-321 up and running 24/7 for almost two years without any problem whatsoever. It is very simple to install with one drive, and easy to add a second drive with both drives as independent volumes (standard mode). [I haven't tried, but I've read that RAID modes might be more difficult.
Summary: I'd say I"m a pretty competent, "Computer Hardware Tech" and I've never had this much trouble getting something to work. I couldn't "find" the device with the provided software to easily find it, once I manually found it, and logged in, the unit couldn't read the HDD.
Summary: Would be nice if the SSH server was enabled by default for shell access - it's not hard to get one online and operational, but it takes some non-manufacturer-supported effort. Also, a feature for changing UID's for NFS users would be nice - alternative is to change UID on all NFS clients.
Summary: I bought this for external storage that can be accessible thru network and my findings werent that good. Dlink advertise this product with 1gbit Ethernet port, but it dont mention that the hardware inside the system is so slow that the gbit is just a selling gadget and not useful.
Summary: If, like me, you plan to use this as a backup disk and you use XCOPY to backup your files, know that this device doesn't implement timestamps like Windows does and as a result XCOPY always thinks the file needs to be copied.
