Ok, so I have an ever aging and ailing Windows Home Server. An original which while still going strong has begun to exhibit signs of time and age. My original WHS served as a storage center for all of the family's photos, docs, music, and movies that I used to stream to another HTPC running XBMC, 3 windows PC's, a few xbox 360s, and of course a smattering of phones and other smart devices. To say the least, the original WHS had its fair share of problems with networking, software integrations, router configurations and general head banging and teeth grinding. None of these were ever really intuitive or straightforward, and all had their fair share of frustration. And all of that was done at a time without kids. Which we all know, suck the living life out of us and vaporize time like an expanding black hole. So my next server would not, repeat NOT, mandate as much time.

Time for a replacement. So where did I start? First I decided that I would value my data over the speed of the machine, as much of it would be used on my home Gigabit network. So speed was not the first priority. Second, I wanted to attempt to ensure some semblance of data protection. After reviewing and reading about all of the RAID types out there I have come to a single understanding. Nothing is guaranteed, and everyone has a different subjective opinion about the actual security of your data across the different RAID types. So in the end, make a backup, of your backup. Third, it had to be accessible by all of my devices in my network and for me especially, be able to be viewed and accessible by my media devices (i.e. Xbox 360, Android phones, tablets, and other Windows computers.) Seems so easy right, three simple requests.

Now on to building.

After running a DS212j at home for a few weeks, I purchased one of these for work (small business) to replace an old server that was annoying to maintain when all it did anymore was serve files.

The DSM operating system is fantastic -- it's a windowed web-based interface that feels like a normal graphical operating system. Functionality is divided up into different settings screens in a Control Panel, and everything is easy to find and adjust. It's straightforward to add users, create shared folders and set specific permissions on them, setup backups, etc.

It's also possible to install apps that extend the functionality of the system. For example, Synology provides a 'Time Backup' app which works like BackupPC with an easier-to-use graphical interface. It basically saves "checkpoints" at configurable intervals, so you can roll back files if you accidentally changed them, like if you wiped out the contents of a document.

Some other reviewers mentioned having a problem with their DS412+ where the USB and eSATA ports don't line up with the slots on the enclosure. Mine didn't have this problem. Although it's mostly plastic, the enclosure looks nice and the fit and finish is pretty good.

I did have an issue when rsyncing to the device; I screwed up the permissions and had to manually log in and adjust them. No big deal -- if I didn't know how to do fix it I also wouldn't have known how to set up an rsync server in a configuration that let me mess it up. It's not something you'll do accidentally.

Unfortunately, Synology's most recently released NAS devices have been having some serious reliability problems. They issued a press release on April 13, 2012 regarding a large batch of NAS with defective hardware.

One Week In (update below)
Preface - I have coworkers who have Synology devices and had no problems at all. With their success I thought it would ramp up my learning curve.

I purchased my Synology 412+ from Synology via Amazon.
I received the device and initial setup was very easy but took a long time as I'm using 3 TB drives (new ST3000DM001 and approved for the device) and configuring the raid (SHR) and the volumes takes a lot of time.

After setting up the device, upgrading the "OS" (DSM 4.0), and configuring the device and base applications, I went to sleep. I was woken up by the device alarm reporting raid/volume had failed. I ran the SMART test from the device and received Normal responses from the drives. I rebuilt the Raid/volumes to have it fail again. I swapped drives with fresh new ones of the same model and have had the same issues. I have used every combination with no joy. I have also only created the SHR raid with no volumes only to have the RAID "degrade"
I contacted support via email (email and forum only)and have been trying the same thing I have tired over and over. Slow disjointed process but hopefully it will work.

I thought my main issues would be getting my ports set-up correctly for internet access and getting my family trained on how to use it.

tl;dr Unstable and not working so far

*Update 4/24/2012
I updated the firmware on the ST3000DM001 drives and it appears to have resolved my issue. I am requesting the manufacturer update their hardware compatibility list to add an annotation for firmware level on the ST3000DM001 hard drives.
Vendor was responsive but troubleshooting was delayed due nature of support structure (email)
Updated from 3 to 4 stars
