The little NAS that could,
I needed a network storage, and I wanted some degree of user-extensibility (hackable). After much research, DNS-323 became an obvious choice, at least based on specification, figures, reviews and user reports. The budget was under $200, and it’s incredible how expensive NAS boxes are in general.
Here are some models I considered and why they didn’t make the cut:
Linksys Storage Link for USB 2.0 Disk Drives NSLU2 an amazingly flexible NAS that’s also cheap. It has a very large and healthy development community for its hacks. However it requires external enclosure and is much slower. NSLU2 also doesn’t spin down the drives by default (reports say you can with some tweaks). Has the least functions out of the box. Very tempting alternative however, due to its being a favorite platform for hackers/developers and consequently a legendary bang for the dollar.
Linksys Network Storage System with 2 Bays (NAS200) follow up on the NSLU2, has two SATA bays, seemed perfect. However Linksys decided to drop a dog of a chip in there, making it slower than even the old NSLU2 out of the box. The chip is also different and odd compared to NSLU2, making it a dubious candidate for development projects. Heat dissipation is also a reported problem, as well as fan noise. It’s relatively new so no development projects (hacks) are centered around it. I wonder with the lackluster hardware if it ever will.
Buffalo LinkStation Pro Shared Network Storage LS-320GL – NAS – 320 GB – Serial ATA-150 – HD 320 GB x 1 – Gigabit Ethernet Has everything–gigabit, speedy processor, large ram-but only 1 bay and comes with a drive that I don’t need. Replacing the drive voids warranty, and the drive doesn’t spin down (big no). Isn’t as well made as there are numerous reports of it failing after a few months. Also a very hackable unit like NSLU2, and were designed to encourage it.
I came into the decision on my DNS-323 with a slight mistrust of D-Link products, after having owned several buggy network hardwares in the past. The justification for the purchase was its reported speed by many, often comparable or beating units more than several times its cost. It’s one of the few “budget” boxes that actually delivers the speed it promises.
It has a 500mhz processor, the Marvell 88X7042 SATA controller and marvell’s 88E1111 gigabit network handler. All proven workhorses. a very efficient case design with small volume/footprint, the dual bay sata with raid, standard linux file format (ext2), the ability to spin down and its operating power efficiency. For the money, there’s really none other on the radar with these credentials.
Receiving the product is another revelation. I’m the obsessive-compulsive type who can see every single flaw, which tend to be plenty on mass produced products these days. I couldn’t find one scratch on the brushed metal sides of this NAS case. The product is very solid, with hefty metallic casing (I don’t think you can find any NAS box made of metal under $200.. or maybe even $500), that actually has a suede rubberized finish on top and bottom. The metal case proved to be important as it helped dissipated the heat of the drives as I turned off the fan with scripts later. It is also VERY spatially efficient, with no space wasted. The only gap between the drives were well thought out as cooling channel. I don’t think it could get any smaller without hurting its function. The speed-controlled fan is very quiet to the point of being nearly silent; an amazing feat due to its size (40mm). I don’t think I have ever seen a small fan that quiet. The lights are discreet, no Christmas colors. The box looked great and exuded quality. I can’t complain about the build quality at all. It’s just well made with solid components. D-link’s accountant must be asleep at the switch.
Installation is easy. You just open the front face cover and slide in the drives. Connect the power and network cable and that’s it. It comes with (or you can download) a software that automatically maps the drive for you. (you can do it yourself too quite easily. it’s not proprietary in any way) The configuration page is also very straightforward. Perhaps a bit too plain vanilla, but what it has just works. Have been using ftp and itunes server extensively. I haven’t tried raid 1 (which reportedly have issues with older firmwares) or the upnp media server. Otherwise I haven’t had problems with the firmware, which I…

Unreliable/unable to recover from hard drive failure,
The D-Link DNS-323 is a dual SATA enclosure, boasting an embedded Linux running on a Marvel board with an ARM5 processor. You put in the drives, and it configures them using the software raid stack from its embedded Linux. It has gigabit ethernet, and as NAS functionality goes, it only supports SMB shares. That’s about where the coolness ends – with the specs. Even though it runs Linux, it is not capable of serving NFS. Even though it runs Linux, it is not capable of using ext3. But I am getting ahead of myself.
First thing I had to do based on the advice pouring from the Internet was to upgrade its firmware to the latest and greatest 1.0.4. Then I put in my 2 x 1TB drives and I started configuring it. The web interface gives the usual choice of jbod/raid0/raid1 – and after choosing raid1, it asked me how much RAID1 I want, promising that the rest will be used for a JBOD setup. I selected a 500GB setup for RAID1, which gave me an extra 1TB of JBOD scratch space I planned on using for stuff like local mirrors and caches. I did a samba mount for the RAID1 volume, dropped about 20GB of stuff on it and then proceeded to test the failure handling of the DNS-323. Power off, pull out one drive, start it up in degraded mode. As expected, the JBOD volume is gone, but the RAID1 one is still going strong, data is still there. I zero out the drive I pulled out, power off, insert it back, and power on again.
This is where the fun started. One would expect the device to reconstruct the RAID1 array, and give me an option to remake my JBOD from the space not being used for the RAID1. Sure enough, the web interface prompts me resync the new drive2, issues a failure, asks for a reboot. Upon reboot it asks again to resync the newly inserted drive2, this time it looks like it is making it through, half an hour later it says it is happy and asks me to reboot. Fine, I reboot, next time it comes up it prompts me to resync the newly inserted drive1 (note – this is the *other* drive that I have not touched, now it thinks that drive is newly inserted as well). This is testing, so I click ok, it fails, asks for reboot; reboot, starts syncing fine, completes, asks for reboot. On next reboot, it asks to resync the newly inserted drive2, and the cycle seems to keep on repeating.
On the positive side, the data continued to be available. But maybe because it was running degraded most of the time, I don’t know why, it stopped being reliable. I would get random read-only errors from the smb mounts, directory tree corruption (files that should be in subdirectories show up in the root of the share), a whole bunch of problems that made me put the thing in the box it came from and send it back to Amazon. I wasn’t even trying to stress test it and it failed miserably. Totally not worth my time dealing with it. How many people that declare themselves happy with the device have actually tested the recovery from a hard drive failure?

Why you should not buy this product,
Based upon its specifications and price, this product seems like a great deal. And if you just need to share hard drives over your network without any security or passwords, it seem to work very well.
Here’s why I’m returning mine.
1. Although the device is advertised as supporting the EXT3 file format (which is more secure than EXT2), D-link’s original firmware apparently had many, many problems with EXT3, so Dlink updated the firmware. Did they re-write the firmware to correct the bugs? No. They just removed all support for EXT3. Unfortunately, they didn’t re-write the manual, so if you read the manual, you’ll wonder where the EXT3 options went, and whether your unit is defective or not.
If you don’t know what EXT2 and EXT3 is, check out Wikipedia. Suffice it to say that EXT3 is better, more robust, and has better protection against data loss. Most NAS devices uses EXT3 by default. Although this device is advertised to support EXT3, it hasn’t since a firmware update in early 2007.
2. Dlink did exactly the same thing with the Disk Utilities, including a scandisk and defrag feature. Again, they’re still in the documentation, but nowhere to be found on the device.
3. Technical support is absolutely horrid. They’ve outsourced to somewhere that doesn’t speak English, understand their products, or understand customer service. I called to inquire about the above issues. Two of the three times that I called, I couldn’t even hear the representative because of what sounded like a very loud fan in the background. The third time, the representative had no knowledge of the product. In fact, when you go through the phone tree, there isn’t even an option for this device, so you just have to select something else and pray that you reach the right area.
I ultimately got my question answered by calling sales and asking to be transferred to a level 3 support technician – they’re in the U.S.
4. When accessing the network share on the DNS-323 from a Windows based machine, you must be logged in to your machine using the username that you entered on the DNS-323, because the “user name” field will be greyed out and cannot be changed when you attempt to access the files. This creates problems if you have different usernames on each computer because you must now set-up the system. Other NAS devices (Synology, Buffalo, Linksys) don’t behave this way, instead letting you change the username and the password when you login. There is a workaround, involving mapping a network drive and selecting the option to login as a different user, but I have too many folders setup to map every single one to a network drive.
5. The password length must be between 5 and 8 characters. Because you must set the username and password on your Windows machine to match exactly with the DNS-323 (see above), you now must make sure your password on your computer is also between 5 and 8 characters. Most other NAS devices don’t have this limitation.
6. Each time you set-up a user permission to access a directory, the system creates a new, different share name. For instance, suppose that I have a directory called “Test.” I choose to allow a user named “John” to access “Test” with read-write permissions. The DNS-323 will create a share named “Test” which John can access. Suppose that I then allow a user named “Mike” to access “Test” with read-write access. The system will create a separate share named “Test-1″ which Mike can access. Mike will not be able to access the share named “Test” and John cannot access “Test-1.” With multiple users, this could be a serious nuisance. Other NAS devices (Synology, Buffalo, Linksys) don’t behave this way, instead letting every user simply access “Test.”
8. The scheduled backup feature does not work properly. I set it up to backup all the files from an older Linksys NAS device. It got about half-way done and then stopped for no apparent reason. To make matters worse, when I attempted to delete the files that it did copy, it gave me an error claiming that the files were read only. Apparently, it set some kind of read only flag on all the files that it copied. I tried changing the flag, but it wouldn’t let me do that either. Yet, I have read/write permissions for the folders and I can change the file names. I just can’t delete them.
