For this review I can't comment on all the features of this unit, which are many from Media Server to Camera Surveillance Station Recorder.

We just use this as a File Server in a Windows Environment with Active Directory. The setup was very easy. Install your drives, I used the WD Caviar Green 3TB drives for my last setup - I have had no problems or issues with any drive I have used on several Synology NAS Drives we own. Plug the device into the network, load up the software it comes with onto your computer. The software will find the drive on your network and from there you can manage everything about the drive.

From the Web Based Management Software I was able to join it to our Domain, create a share, assign it a Static IP Address and setup email notification for problems. I was also able thru a few simple clicks to tell it to go out on the Internet and update its Firmware; probably the simplest Firmware update I have come across yet.

I didn't get too far into timing tests for performance. For sure I can say the transfer rates to these new NAS drives was as fast as previous setups I had with dedicated Physical Windows File Server. The units that get heavy use from multiple users, I setup with the 2 Network Ports and Link Aggregation and I can tell the transfer performance on these are at least 20+% faster than the old File Server with 1 Network Card.

For testing purposes with these setup as Raid 5, I have pulled out drives and it never missed a beat. Even had 2 unplanned loss of electricity over the last year and was able to start up these NAS drives and all the data was fine.

The only bad part I would say is the time to build a Volume. E.g., 2 drives came late so I started out the NAS drive with 10 drives which took almost 24 hours to build the 10 drive Raid 5 Volume, then I installed the 2 drives latter when they arrived and it took 36 hours to setup the new Volume with 12 drives.

I have 3 Thecus models (N5200, N5200 Pro and a N7700). I will compare the Synology DS2411+ to these. I use Network Appliance storage in my day job. First I purchased a Thecus N5200 for home use, then later the N5200 Pro and N7700 for some small workgroup level projects before the NetApp budget came through.

The Thecus hardware was innovative at the time (compared to say the Buffalo Terastation, had one of those too). It supported a few additional modules (IP Cam, DDNS, etc). Thecus root/shell access is disabled by default, but much easier to obtain than the Terastation. I've never had a Thecus hardware failure in 12 box years of use, but I lost a RAID5 array due to simultanous drive failures once. Performance is tolerable, not outstanding. While advertised as capable of iSCSI (for virtualization) only mapped LUNs are presentable, no virtualization of LUNs. iSCSI performance wasn't great on the 5200 series.

Thecus has absolutely lousy support, you'll have to rely on the web forums. The Thecus web GUI is sprinkled with awkwardly translated English. Once a Thecus RAID array is destabilized (as in drive failure) there's no software switch to turn off the buzzer. No physical switch either. Thanks Thecus, my ears are still ringing from the last drive failure.

Purchasing a DS2411+ for home use, what a difference! The Diskstation OS is like a virtual desktop in a web browser. You can log in from one PC and start a large file copy job, then go to another PC later and (with the same account) see the progress of that job. You can copy files to and from your local PC to the box (through a Java plugin), or from a drive mapped on the DS2411+ to another NAS box (without going through your PC). NAS to NAS directly ! There are 30+ optional software modules available as well.

Performance is outstanding, with 8 7200k RPM SATA2 disks (Seagate 2 and 3 TB) in Hybrid RAID (based on RAID6 with DP or double parity disks (2 spares)) I get sustained 80 MiB/second write speeds over the network. Supports link aggregation of the two network interfaces.

Setup was simple, after inserting 20 TB of raw disk storage, it formatted and created a SHR2 (RAID6 DP) partition in under two hours. My Thecus N7700 took two days to create a 7 TB raw disk volume!

I haven't had to call Synology support (yet). The DS2411+ does come with a 3 year warranty. No broken English found yet either.

Thecus:
Pros: cheaper ?
hardware is OK for consumer use.
Most of them have a LCD display.
Cons: software, OS and features are limited. Web admin GUI is primitive.
Few software releases or optional modules.
Obvious machine translation of the GUI into English.

Synology DS2411+:
Pros: Diskstation OS is amazing
Great number of optional modules
12 hard disk slots. Very few other 12 disk SOHO storage options.
High quality hardware.
Cons: Built-in modules (web server, wordpress) may be difficult to keep up to date with latest security patches*
Difficulty adding into ADS / Windows Active Directory domain. Failure doesn't leave detailed logs.

* OK, I have only installed two modules so far, the wordpress module requires mysql which is a little tricky to set up at first. Personally I wouldn't recommend running this device as an Internet or external server without fully understanding how to patch all software and applications, but I'm less concerned with running it on my LAN.

I don't have a DROBO, I considered one but at that time DROBO wasn't doing NAS much. The Synology has a similar expand on demand RAID feature (SHR) which I've not tested yet.

Conclusion:
If you can afford a NetApp for home use (and the power bill to run it) then go for it. If you want a highly capable SOHO NAS then the DS2411+ is well worth it. My Thecus boxes will be on eBay soon. :-)

It seems to me that the recent NAS products from Synology are getting better. I have been using DS2411+ for about half an year and did not encounter a single problem. It is quite and fast. The DSM interface is also easy to use. At first I used 8 HDDs to form a single Raid-10 array for maximum data protection. 3 months later I decided to add another 2 HDDs to expand the original Raid-10 array. No problem. Simply follow the steps shown in the DSM interface, and your new HDDs will be online in minutes. It doesn't ask to shutdown any services so my users can keeps using it like nothing happened.

I personally own a much cheaper 2-bay NAS from Dlink so it is not comparable to DS2411+. I don't have much experience on QNAP products so cannot say much about their comparison neither. But with the overall good quality with DS2411+, I'm looking forward to trying other Synology product. Hopefully the price could be cheaper though.

This device greatly exceeded my expectations. It supports more hard drive models than it claims to. The UI is HTML5 based and flawless. The built-in security features have effectively blocked and reported repeat unauthorized access attempts. The community support is great. The OS is easily expandable to support many common Linux dpkg's. I am very pleased with this device and would definitely recommend to others.

Hi, just wanted to post some clarifying information regarding this unit (which I ordered today) for questions that I had answered by Synology.

1) Even though the product feature page for the 1511 and the 2411 are slightly different, both units have the same exact features. Basically, any of the stuff that people have written about that they can do with the 1511, can be done with the 2411. I know that it was *most likely* the case, but I wanted to be sure.

2) The unit has a different expansion connector, so you can't use a 5-drive expansion with this unit, only the 12 unit. The 5-drive is eSATA. Forgot what this one was.

3) The link aggregation only works with a managed switch where that can be set up. Apparently, it's somewhat complicated and usually not worth the effort to try and support it. E.g. it's hard to fill up a gigabit bandwidth, and the network hassles may be more than it's worth.

right now giving this 5-stars in anticipation of it being a 5-star product based on the 1511 reviews and how I expect it will fill my needs. Will adjust accordingly if need be.

here is the story in it's full glory:
[...]

to make it short: there is an ongoing issue where copying files via windows share just stops and results in a failed copy. As a user, you do not know whether this is an hardware issue, or a software issue and whether this effects your data in any way. This is the main functionality of a NAS and this has to work but sadly it does not (according to Synology you should leave the NAS running all the time to avoid this error ... not joking)
According to the above mentioned thread, some people have reported this issue in the 1st half this year and as of the latest update (yesterday), Synology was not able to fix the issue.
My advice is to avoid this hardware until they finally provide a fix.
