2 out of 5 eggsKeep Shopping

Pros: 802.3ad Link Aggregation
RAID Levels 0, 1, 5, 6, 10, JBOD
Hot-Swappable Drives
Quiet/Noise Level
DHCP Server
ADS/NT Support
Supports XFS, NFS, AFP, and SMB/Samba filesystems
Bonjour, UPnP AV, iTunes,
OS-Independent, HTML Setup
Ability to install custom Modules for additional functionality (Twonky MediaServer, FTP Server, Bittorrent, SQL, Image database sharing....)
clean, well-manufactured

Cons: Write Speed
Read Speed
Consistent Performance/Operation
DDNS support
DHCP client
Clarity of UI, uses confusing/non-standardized naming conventions, some UI options and descriptions (if present) written in Engrish
Ability to upgrade RAM without voiding warranty
Module installation/setup
Confounding HTML Configuration
Known bugs/vulnerabilities in supplied firmware with no patches, hotfixes, or support from manufacturer
Things that should be enabled or at-least toggle-able by default in UI require Third-Party Module Installation (SSH, FTP Client, command-line administration, etc)
Manufacturer Support
Availability of alternative/user support
Thecus UI, availability of third-party UI

Other Thoughts: TLDR: Don't.

Purchase based on price-point and the support for RAID levels 5, 6, and 802.3ad/Link Aggregation. Operating 4 x Seagate 1.5 Tb HD

RAID 5 - Performance can be described as an atrocity against humanity. Though confirmed to be operating gigabit ethernet, it's overall read/write and throughput performance is intolerably slow (usually under 11Mb/s, burst never reached 15Mb/s).

Reconfigured to RAID level 1+0, and the performance picked up about 20%, but still unsat for anything requiring performance, or stability.

Does everything it claims, though the UI is unclear in most places, and undescribed or completely opaque in a few. No DHCP client support, requires static internal IP. No DDNS for public FTP/SSH/HTML. Network volumes disappear from file manager or undiscoverable randomly without log errors. Some basic administrative abilities require third-party module installation (SSH, telnet, FTP). Processor and RAM not capable of performing all features adequately.

1 out of 5 eggsMake sure you put the keys in a safe spot

Pros: Cheap, easy to setup, hackable, full featured NAS, with enough speed for most home use.

Cons: Its apparently not possible to get replacement keys for the Thecus devices. Aka, you have a worthless piece of metal if a drive fails and you can't find your keys.

Contacting Thecus support is worthless. All they could tell me is that different models use different keys, and in fact it sounds like even within a given model the keys change depending on the manufacture date.

The best part is that the different keys don't have different part numbers, and therefore I have about a zero chance of getting the right key if I buy a replacement.

Other Thoughts: Suggestion:
If you buy this device, tape at least one of the two keys to the back of the device to make sure you don't lose it.

If it wasn't for this one oversite on not even being able to BUY a replacement key, I'd probably give this unit 5 stars. However, its worthless and stupid that something this simple is not possible.

4 out of 5 eggsproof that I am a serious n00b

Pros: Bought this because my next project is a NAS server. People seemed very pleased with this product and I am too. It has lockable bays for security and is really quite adorable.

Cons: I feel really dumb for not realizing it was an empty case: no actual storage drives included. I looked everywhere on the product listing to figure out whether it was a case or a server, and thought I knew what I was purchasing. All the other items I looked had an indication somewhere that there were no storage drives included. This is entirely my fault for not understanding what I was buying, but still, I think it would be smart of Newegg and/or Thecus to say so somewhere in the product description. I think it is cool and plan to keep it. I just have to save up a bit to afford the actual storage now.

Pros: Still setting up the drive. Just FYI, my device required DDR SODIMM, not DDR2 or DDR3. YMMV

Cons: none so far.

1 out of 5 eggsDinged up but works like a champ

Pros: Multiple NAS functions that are unavailable on more expensive models similar to the N4100pro. Great device- see the cons for the low eggs.

Cons: Big fat ding in the top of the case when i got it. Needed the network storage so bad at the time i didn't complain to Newegg. When i recieved the box it was already opened obviously not mention it didn't even arrive in a newegg box which was really weird? but had a newegg shipping label on the outside. Drop Shipped from California(literally i think). I have a feeling i ended up with someone's open box as a new device which this is the 3rd time i have bought some thing from Newegg as new to realize it was indeed missing parts or was an open box sold as new. Like all the other low eggs only one raid volume.

2 out of 5 eggsSLOW

Pros: I pulled this out of the box and thought "Wow, this is cool!". I was able to configure a variety of storage options very quickly. The user interface is simple, web based and easy to use. Upgrading the firmware was not 'simple' but following the online instructions, it was not a terrible experience.

Cons: It's unbelievably slow. Depending on what you want to do with it, DO NOT USE THIS FOR VMWARE!!!!! Let me say again, DO NOT USE THIS FOR VMWARE. It took nearly 8 hours to install Ubuntu and run the updates. So, it's absolutely NOT a good solution if you want to do anything that involves disk IO. I contacted support and the response was (in a nutshell) - setup vmware with blah de blah and understand that you bought a low end device so don't expect much...

Other Thoughts: It's quite stable so even though the processor runs at 100% while doing anything (such as building a new virtual machine) it doesn't crash (gota love the linux OS they put on this device!). I also installed (for $32 of my hard earned money) an "unsupported" 1GB RAM stick which has taken the installation time of a new "vanilla" virtual machine down from 8 hours to less hours (I haven't had time to actually test this out, I'm making a wild assumption that the meager 256 MB RAM they shipped it with was not enough).

All in all, it would make a better backup storage device, assuming you don't care how long your backups take.

5 out of 5 eggsFantastic Product For My Needs

Pros: Reliable - Great Value - Good Speed (1GB Upgrade) - Excellent Manual - Very Versatile - Great Web GUI - GB Ethernet - Quiet

Cons: Doesn't restart automatically after power outage. Needs 1GB RAM upgrade.

Other Thoughts: I bought this unit after buying a Raidon product and the difference in quality and usability was night and day. Not sure what went down with the user who posted a few days ago and complained about the Chinese downloaded manual. My manual was included on one of the provided 3 CDs. It walked me through, step-by-step, the basic setup, then released a very well written 100+ page manual that told me exactly how to set things up.

In my case, I'm using the Thecus to serve Blu-ray and DVD ISO files to a Dune media server. The files are HD uncompressed and I just wanted a reliable source for my media. The Raidon I had previously bought, didn't recognize a bad drive (dead on arrival) and never booted up properly. The Thecus recognized the bad drive and just went right on ticking. I ordered a new drive and it accepted it, no problem at all.

So, with 4 Samsung 2TB drives and an out of the box 1GB RAM upgrade, and top shelf manual that left me with no real questions I am very happy.

4 out of 5 eggsGood NAS for the money

Pros: Supports multiple RAID configurations, ext3, ext4, ZFS -- and with the firmware update supports iSCSI and thin provisioning. Lockable drive bays, and a nice LED status display. Allows LACP port aggregation (running a 2Gb link to my switch) as well as several other network failover configurations.

Cons: Thecus should equip it with 1GB of DDR2 PC400 SODIMM right out of the box. 256MB is insufficient. Just order a 1GB stick along with the unit (around $30) and you will have much better performance. Despite what others have said, Thecus does not put a seal or tape over the SODIMM to prevent an upgrade. USB UPS monitoring doesn't work, (Thecus claims it is fully supported) even after installing the UPS module via the gui. If you want folder quotas, you have to use ZFS and not ext3, but in this iteration of Thecus' firmware, ZFS doesn't perform as well as ext3.

Other Thoughts: If high performance and more advanced features are important to you, you might want to consider the N4200eco instead of the N4100PRO. For a media server, iTunes server, backup box or home use, this thing is an excellent fit. Remember you will get MUCH better performance if you run a Gigabit LAN and you add a 1GB stick of RAM.

5 out of 5 eggsExcellent and simple

Pros: Excellent little NAS with alot of features you normally wouldn't get at this price point such as locking drive cages, dual Gigabit adapters and a large quiet chassis fan. It was easy to set up, but ignore the "quick start" guide because it's generic and wasn't applicable to my unit. Comes with a patch cord, and lots of mounting screws for either 2.5" or 3.5" drives.

Cons: Documentation included is quite poor. Go online and download the proper manual. Good news is, it's easy to find on the Thecus website.

Other Thoughts: If you need iSCSI then go with the next higher model, but for a soho nAS, this is an excellent fit. By the way, unless you are asking for trouble, get RAID class drives, not WD Caviar or other consumer drives. RAID class drives have TLER technology, and it will save your bacon if you ever have to restore from parity. Plus, they have a 5 yr warranty.

1 out of 5 eggsChinese garbage

Pros: It is pretty, quiet, and compact. Excellent read throughput.

Cons: An extreme PITA to work with. The web interface is painfully slow. The manual (.pdf has to be downloaded) was translated from Chinese to English by software, and is generally missing verbs, nouns, direct objects, etc. It is extremely difficult to understand, and the screenshots in Chinese don't help. The English really makes absolutely no sense. Really, seriously, I can't stress it enough, the directions are worse than useless and generally contradictory.

The directions to upgrade the firmware are inaccurate. The specifications listed in the manual both pre and post firmware upgrade are innaccurate. It is impossible to use ZFS as your file structure in a RAID array. It is extremely difficult to get modules to load and function properly. Write times are impossibly slow, although read times are very good.

Other Thoughts: I'm not a Linux "guy." I've been doing data center and systems admin work for about six years now, and figured I could probably muddle through the web interface just fine. For the most part, I could. However, things are so badly written that if I don't know exactly what I'm trying to do, there isn't any way to discover it. I had a Linux guy come over and help me get a module working so I could SSH to the box and work from there, and that was helpful, but more than I really want to mess with.

I have nothing to say about the hardware reliability, as I haven't used it long enough to be sure. I do know that unless you are very, very patient, or are very comfortable working in command line Linux and are still pretty patient, this isn't the NAS for you.
