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 throughput though; it does the job as a backup device for home use though
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. Unfortunately, I found this out the hard way as I updated the firmware from 1.02 to 1.03, then spent countless hours troubleshooting the problem. I have two Western Digital WD1001FALS Black Caviar 1TB drives installed.
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. So what you are after is going to make a big difference in how happy you are with this product. First and foremost, THIS DEVICE IS SLOW. Forget what it says about the network connection speed...you'll never come close to it.
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.] It's also very easy to set up a dynamic dns name and to set the unit as an FTP server.
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. I'd've rather dealt with changing the UID of my new user on my new NAS than on my rather long in the tooth desktop (with crap scattered around the filesystem needing manual chowning...
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. I cannot do the 125mb/sec transfer rates as 1gbit truly support with the proper equipment (hardware) and settings.
Summary: I picked up the DNS-321 after exploring several options for a RAID 1 NAS solution. From the specs, it was exactly what I was looking for: affordable, offered support for 2 drives in RAID 1 configuration, and provided media server support. In practice, I ran into a lot of issues, and I suspect these concerns apply to the DNS-323 as well as the DNS-321.
NAS (Network Attached Storage) Has Come a Long Way

Summary: My first installations of network attached storage (NAS) devices was in about 1982 or 1983. Before personal computers came equipped with hard drives, Corvus offered 20MB and 40MB network storage devices that were about the size of a breadbox and cost between $2,500 and $3,500. The network cards were an additional $200 each. At the time, we couldn't imagine how we would fill up so much space.
Summary: I bought this NAS as an addition to my file server as I don't have any more drive bays available. This unit was purchased to supplement my 3GB file server with more file space. With my file server I am used to getting at times a max 60 MB/sec in transmit speeds but on average 30-40 MB/sec. With this unit I am only able to get 12-14 MB/sec. So when you are used to transmitting files in 1 minute and now it takes 6, it can be kind of disappointing.
