After all of the positive reviews for the Synology DiskStation 2-Bay (Diskless) Network Attached Storage DS211J (White) I saw that an updated model was just released and decided to try it out.

Coming from an iomega StorCenter NAS and a NetGear ReadyNAS, I have one word for the DiskStation: WOW.

The D212J makes these other product lines look like thumb drives - mostly due to Synology's DiskStation OS. This feels like a full-fledged system; more or less a dedicated server. Faster, quieter and exponentially more customizable without being overwhelming. And so far, it's proving to be much more reliable.

Every feature and detail (and there are far too many to list), from start to finish, has been thoroughly developed. From the box, to the installation CD software (which remotely installs the OS on the unit over the network), to the remote access features and mobile apps, no feature has been left out or unpolished. Completely solid, every step of the way. If you're looking for a full-featured media server, backup server or file server, you'll find it all here in top form. You'll even find surprisingly well developed web and database server options.

The whole OS feels like if you took the best of Mac OSX and Windows 7 and blended them together. There's some serious R&D and talent behind this thing. It is rare to find a product so thoroughly excellent.

One of my more 'wow' moments: the DiskStation OS detected my router - with a custom firmware - logged into it, and tweaked it to allow remote access and torrent/usenet downloading through the NAS. In one click. Yeah.

(note, my review for this originally appears on Review Lagoon and is reprinted here)

Storage. For almost everyone that owns technology, storage is the very fabric of life. It doesn't matter how entrenched in tech you are - storage need eventually raises its ugly head. When it does, we scramble for a "storage solution" which is commonly equated to "more"; more GBs, more TBs (maybe even PBs for some). Some people are more worried about the format of storage; do I need a bigger old school hard drive or should I go for faster SSD solutions? Unfortunately, the "solution" part of "storage solution" is rarely looked at from an ever-growing need point of view; how do I access my storage?

Ah, yes. "The Cloud". This decade's biggest buzz phrase and an explosive industry all on its own. There are so many solutions it can make one dizzy and each one promises SOMETHING that "the others don't have"; be it more storage, automatic syncing across devices - you name it. Unfortunately, they all have shortcomings - ensuring that none of them provide exactly what everyone needs.

Why the DS212j?

Frankly, I was fed up. I knew what I needed; a lot of space, no restrictions, accessibility from every single device and PC (local and internet) and the ability to easily share with family and friends. This particular combination of needs simply doesn't exist with a commercial service like Google Drive, Box or Dropbox. Drive makes it a pain to access your drive contents without syncing. Box wants to cap the size of your files. Dropbox just doesn't have sharing flexibility. None of them provide adequate storage space for a heavy demand user like me and most of the mobile apps proved completely archaic.

The list goes on and on.

Nice, I upgraded from DS110j.
Now i have 2 HDDs in Raid (Mirroring)(2 Seagate Barracuda 1 TB drives)
I use Western Digital green disk for my DS110j, no problems so far. (1 year using 1TB wd10ears)

I use it for:

* 1 Gigabit connection, (It works with your current 5e cable)
* Backups (Faster backups "LAN")
* Remote administration via Web
* Downloads (torrents)
* Documents uploads and downloads (It doesnt matter if i lose my encrypted pendrive)

* No cons here :)

* HDDs setup with error checking can take about 3 hours

Ideal Buy if you are looking for a NAS.
Nice upgrade for home users.

For the home or small office, the DS212j provides peace of mind for your data. I put two 2.5TB drives and followed the installation instructions to find that I finally had a place for my stuff.

1. Preparation
Make sure you are buying supported drives for the device (note: I put WD caviar greens in mine). Make sure you have a cool spot with power and networking ready.

2. Installation
Installing drives was trivial with my trusty phillips screwdriver (I call him 'Phil'.) No cables are necessary. The SATA drives mate directly with the built-in board. Then you fire up the provided DS software to install the runtime and get connected. Follow the steps to create the desired volume(s) and turn on the services that you want running. (Note: I had firewall issues with one of my computers when trying to connect.) There's even a "personal cloud" service that you can turn on if you're brave. Since I'm using mine for home I didn't try any of the built in email or LDAP services. Your mileage may vary.

3. Transfer
The DS212j has two USB connections on the back, which was perfect for me. I connected my WD My Book to it, and then was able to transfer my files directly to the new drives (rather than over the network). I was also able to use the Android apps for accessing files, photo, music and video. However, I don't currently have any DLNA devices so I haven't tried that yet.
