This thing is fast/scalable/reliable/configurable/expandable/bulletproof and worth ten times what it costs. For the money you get a full function NAS with two drive bays, Linux OS with plenty of really top shelf apps, support for raid arrays and JBOD, thru-the-internet accessability, dlna media server, audio and video apps, excellent disk management apps, solid group/user creation and mgmt, a web server app, ddns with 'no-ip' support and a host of other very useful file/data sharing utilities. Call Synology tech spt and you won't get a tier-1 zombie - rather you get a very knowledgeable competent tech who knows the product inside and out - very impressed! I've used most of the network apps and so far they work perfectly.

Cons: This is not a con but be advised: if you're populating the NAS with large drives (I populated my NAS with two, 2TB drives for a max capacity of 4TB), initial drive preperation will take 8-10 hours to complete - for each drive! I called Synology tech spt to find out if there might be a problem and they explained that the NAS drive prep utility goes thru an excruciatingly detailed surface scan at the outset thereby eliminating issues with bad sectors and other related problems once the drive is placed into operation. THere is a less time consuming drive prep offering but they recommended the full scan - and so do I. Find something else to do while the scan is running. Also; I bought my NAS to use primarily as a DLNA media streamer. It does that flawlessly - this thing is bulletproof, I have purposely tried to add and delete shares/folders/users/etc etc to try and confuse this box. It continues to operate flawlessly - I'm amazed and impressed! The Synology folks surely did their homework.

I bought this and 2 Samsung F4 2TB drives. I have never had a NAS but after another hard drive crashed and I "nearly" lost my family photos, I broke down and decided to spend the money on a NAS with a raid. I searched for weeks before settling on this after reading reviews etc. Actually this model had just came out but all the reviews for the previous Synology Diskstations were good and as this one is no different.

I don't know what I was expecting but the putting it together was easier than I thought. Just slide in the hard drives, set a few screws, plug it in, wait for the blue light to stop blinking (it takes a couple of minutes the first time as it sets itself up) and you're nearly done. Install some tiny software and log into the diskstation. Set up a volume (choosing if you want to raid or not) and then start making share directories. I read another review on here saying it took 8 hours but it had it done in less time than it took me to watch a TV show for my 2 2tb drives raided to make a 2 tb volume. It took me way longer to organize my own files than it did for the diskstation to create the volume. Now it took a few hours to move my 500 Gigs of data but that took me some time because I was moving files from several computers on my network.

This is really the future of super simple home networks. I replaced my main hard drive in one of the computers with a SSD which is amazing and from now on I save all my files on the Diskstation. I just made shortcuts on all my desktops.

And yeah I know this review might not be all that helpful because I barely scratched the surface of all the features this thing is capable of doing, but I'm a simple user :)

This device is replacing a Linksys NAS and seems to be doing fine.

The installation of drives is straightforward as is the configuration. It picked up an IP from DHCP and the Synology configuration program found it right away (I will likely change it to a static IP in the future to allow shares to be picked up on a reboot).

Speeds are fine. I've got mine hooked up to a Trendnet gig switch and it works great. I've got a variety of files stored on it, photos, video and miscellaneous stuff.

Why have I marked the star rating down? I tried copying some files. The copy failed leaving a directory out there. I then attempted to delete the directory and got messages the directory was not empty. I've tried every method to delete the directory, including logging in as root to the DS211j and trying to delete from the command line as root. No luck.

I placed a post on the Synology forum on Dec 15 and as of Dec 20, have received no response. Ok, so that is not the official support channel. I can accept that.

However, I also opened a support ticket on the 15th via their website and other than an acknowledgment that they received the ticket, I've seen no activity. I don't believe a 5 day wait with NO communication is acceptable.

While a nice product, I tend to think that you are on your own for support. I would be quite hesitant to purchase this system for business use knowing what I do now.

After being impressed with a friend's 210j, I got this.
Things that either my friend or I had messed up originally:
1. He had some issues with his WD green drives, so I got the most recommended drives for this (Samsung f4 2tb drives). They just work.
2. I recommend NOT using the synology router config program or the synology dynDNS program--do the forwarding and dynDNS through your router. This gives you better control over where your programs and ports point.
3. You have to set up 3 standard folders: Video, Music, Photo. You have no choice on these--they have to have these names. Audiostation and audio-DLNA read from a folder named "Music"--likewise with photos for PhotoStation/photo-DLNA, and video for video-DLNA. Trust me. Just use this structure. The ways around it (though they exist) are not worthwhile.
4. I formatted my drives to EXT4 (the newest Linux standard) in case I needed to read them outside of the Synology unit. By default it uses a Synology-created format. Either are good choices, but I am a paranoid person when it comes to data redundancy.
5. Indexing/thumbnailing several hundred gigs of photos really did take the DiskStation 2 weeks of 100% CPU usage 24 hours a day. No big deal, it really did finish. If setting up another, I would have used the Synology Assistant "easy importer" for this--it uses your desktop CPU to do the indexing/thumbnailing as it transfers instead of having the less-powerful NAS do the data slugging.

Overall, the DS211 has been easy to configure and use. If you don't like tinkering or don't know what a network port is then a NAS might not be for you, even with this one being fairly easy among your choice of NASes. If you can set up a router with port forwarding then you are fine.
