5 out of 5 eggsBest NAS from a price/performance aspect

Pros: You can't beat this NAS at the ~$100 price range. You will have to spend at least 50% more to get better read/write performance. I get write speeds in the 70-75mb/s range consistently, and read speeds in the 80's-90's, in Raid 0.

Cons: None in this price range.

Other Thoughts: I was a little disappointed with my read/write speeds until I did a little research. Removing unused protocols and enabling jumbo frames on my adapter (not the NAS, but on my network adapter) yielded nice results.

4 out of 5 eggsGood stuff

Pros: - Fast, easy setup right out of the box
- Product does exactly what is advertised (so far)

Cons: None to speak of

Other Thoughts: I bought this mainly to move streaming from my laptop to TV, and keep my laptop out of that loop. I wasn't too crazy about working my disks like that for very long.
This box and software does exactly as the documentation states. And nowadays, to buy something brand new, get it home and it is not broke or faulty, you have done something remarkable.
I have bought far too many things made in Asia that are not what the advertisement says they are, and are total junk. As good as this equipment works I bet it is not made overseas..

5 out of 5 eggsExcellent little NAS for internet users

Pros: * Lower cost than competition
* Basic plug-and-play
* A lot of hidden features and applications
* Still supported (last firmware update 9/30/13)
* Integration with Dropbox, Flickr, Youtube
* JBOD, Raid 0, Raid 1 support
* Extra USB ports for external drives

Cons: * Hidden features may require technical knowledge
* Tablet/Phone web UI is a bit rough around the edges

Other Thoughts: Picked this up a few weeks ago from a close-out auction. Expected some basic NAS features and was going to use it to share some drives on my network. Was very pleasantly surprised to find features such as Flickr and Youtube upload support, Dropbox support including a .torrent watch folder. Automated torrent and NZB download support. Media streaming. Extensible through many applications. If you search the net you can even find instructions on how to install plain old debian on it (which is why I bought it, but now I find no reason to).

There might be easier (and more expensive) NAS units for the non-technical folk to set up and use, but if you can poke your way around a fairly friendly UI, aren't intimidated by many configuration options, and looking for a little box to just pull down from the internet, this just might be for you.

2 out of 5 eggsGood for the non-tinkerer

Pros: Easy setup. Good for anyone who ONLY needs a network storage solution and nothing more.

Cons: Configuring permissions do not work as you would expect.
You cannot install your own OS
The only cloud storage solution available is the terrible Polkast
Very very slow

3 out of 5 eggsFollowup to previous review

Pros: Print server, hackable - get into Linux shell, 3 USB ports, web server, ftp server, mySQL, Python, DropBox integration, auto-sync with another NSA, JBOD (two volume) or JBOD (combined volume), RAID 0 & 1.

CPU is as fast as a Atom N450. If you know Linux, you will have a blast playing with essentially a cheap Linux box.

Cons: RAID 0 and 1 are slower than JBOD (1 drive). I ran many benchmarks and unbelievably the RAID-1 was considerably slower than JBOD with 1 drive. It's likely the RAID is implemented in software, and the CPU can't handle it.

Other Thoughts: Here are my figures transferring a 3.8Gb ISO file:

JBOD RAID-0 RAID-1
Read 1:23 1:30 1:53
Write 1:17 1:18 1:30

Here are figures for transferring 1.0 GB of Windows System32 files (4077 individual files)

JBOD RAID-0 RAID-1
Read 4:00 4:18 4:26
Write 1:12 3:31 1:48

It's amazing that the RAID-0 is the slowest in Writes. It might be possible that the NAS caching algorithm is not optimized to write to 2 drives at once. I also notice in using RAID-1, the mirror synching occurs *after* the data is written to the 1st drive.

For the money, this level of performance is tolerable. But if you are seeking a fast server replacement, look elsewhere.

5 out of 5 eggsVery Happy

Pros: Very fast, low power features, print server (replaces my HP USB JetDirect), expandable via external USB drives, feature rich. Set up in 15 minutes, including formatting my 2GB drive.

Take the time to change your network to Gigabyte ethernet and enable jumbo frames the NAS and your PCs for best output.

Cons: Very light weight, seems to be sturdy enough.

Other Thoughts: Ran a benchmarks from my Windows XP64 system with 1gb ethernet Dlink hub, copying 3.8gb ISO file:

To external USB 2.0 Fantom 1.5gb drive --> 2:08
To Zyxel NAS --> 2:23
To Zyxel NAS after changing to 4K jumbo frame --> 1:39

My NAS only has 1 drive, a WD WD20EZRX.

5 out of 5 eggsReally decent for the price

Pros: Low power consumption
Hackable to a point, you can gain root access to SSH and Telnet and really own the box like you should be able to.
Able to install other OS to replace the stock setup (requires some extra knowledge)
Decent performance from NFS addon module.

For NFS from Mac Pro Early 2008 model to NAS I see speeds of:

About 35-45MB/s Write RAID0 (striped) - during write I did notice that the CPU was pegged out at 100% so this is the slowdown during write.
About 90-95MB/s Read RAID0 (striped)

Using the iperf utility to test my network speeds (installed 3rd party addon via ssh with slacker utility) reveal I have a good network in place:
Both directions testing show 112MB/s which would match the 1Gb network wire speed (this just shows what your max network speed could ever be, not what you will actually get.)

Cons: Could have a faster processor as this seems to be the bottleneck for faster write speeds when using RAID setup.
Could have more RAM too not sure if it really needs it though.

Other Thoughts: To those that are "Getting about 10-12MB/sec transferring data":
This is a limit of your network, you are likely connected using a 100Mb network (still very common in home office networks even most N speed WiFi routers have 100Mb wired LAN)
To "fix" this you will need to upgrade your network to include 1Gb routers / switches / hubs.

Running 2x 2TB drives (one seagate and one western digital)

5 out of 5 eggsGreat Value

Pros: Overall, a good value, setup was easy with one gotcha (see below), speed is fine, worth the money.

Cons: Cheap looking and cheap feeling, documentation could be better.

Other Thoughts: I originally bought a Synology DS112j that I was VERY happy with. I returned it because it's very expensive and only had one drive bay. I bought this one instead for $75 less, and this one has two bays so I can RAID my disks. The Synology has a much cleaner, more intuitive admin console and just looks and feels like better quality. However, the ZyXEL, though it looks cheaper and has a more cluttered, less user friendly admin console, works perfectly well and I just don't think the Synology is worth more than twice as much. It's not THAT much better.

Here's one gotcha I ran into setting up the ZyXEL NSA320. I took the disk that I had in my Synology and put it into slot 1, and a second clean disk (same exact model) into slot 2. The ZyXEL started up, but never finished initializing, so the setup program was never able to recognize the NAS. Since I have spare disks, I took out the used disk from slot 1 and replaced it with a clean disk. I rebooted the NAS and it then worked as expected. The documentation doesn't mention this at all, but I could see this tripping many people up. I suspected it would be a problem so I knew what to try right away. But I am an IT professional - I do this stuff for a living - many others don't and this will cause them problems.

However, once you get past that, this box works as advertised. I only have it for a few hours but my first impression is very good.

5 out of 5 eggsGreat features for the price, reliable

Pros: Great features for the price. I needed the RSS downloader and a DLNA server to move from an older Mac Mini over to something headless, and this fit the bill. It's tough to find these features in lower end NAS offerings. The web interface is clean and fast. Handles any size drive I've needed to throw at it and never freezes or gets hung, at least not yet.

Cons: It would be nice if the DLNA server did demuxing (not transcoding) of content, which should be reasonable even with the ARM cpu, but you can't have everything. No eggs off for that.

Other Thoughts: I didn't try the included software, use the web interface.

2 out of 5 eggsDied!

Pros: Was great while it worked, fast, seemed reliable

Cons: Died with the system light blinking. Will not discover over network. Tried rebooting, hard rebooting, and attempted auto firmware update, it didn't even try to do that. No it is just a brick. Sad!

Other Thoughts: I have purchased a lot of other ZyXel products that work great and well. This was very disappointing.
