Unboxing and Setup Impressions
The Synology DS1812+ package weighs in at 14 lbs (approx. 6.3 Kgs), with the diskless unit coming in at 11.5 lbs (5.1 Kgs). The unit has a built-in PSU and has a desktop form factor with dimensions of 6.2" x 13.4" x 9.2". Along with the main unit, the package consists of the following components:
- Quick Install guide
- Software / Utilities CD
- AC power cable
- Two Cat5 cables (3ft each)
- Two keys for the hard drive bays
- Screws for mounting the hard drives to the bays
The front face of the unit has 8 vertical bays arranged side-by-side with a power button above the center. Status and alert LEDs are to the left of the power button, while the two network status indicators are to the right. On the rear side, we have two 120mm fans taking up most of the space. To the right of the fans, we have four USB 2.0 ports, one eSATA port and the two RJ-45 GbE ports. To the left, we have one more eSATA port and two USB 3.0 ports along with the the power plug receptacle. We would have like some of the ports in the front side of the chassis for easier access. The SD card slots are unfortunately relegated to the entry-level versions only and noneis available on the DS1812+ (perfectly acceptable, given the target market).
On the software side, the Disk Station Manager (DSM 4.2) is a joy to use. A lot of flexibility is provided, along with a number of interesting features. The downside is that it might be overwhelming for some consumers. SSH access is available. This provides us an avenue to get information about the unit without a full-length teardown.
Synology provides support for Disk Groups (a collection of hard drives in the NAS). Each Disk Group can be configured in either SHR (Synology Hybrid RAID - an automatic RAID management feature providing for single or dual disk failure resiliency) or with a manual RAID level. The available RAID levels for manual configuration are dependent on the number of disks in the disk group. Multiple volumes can be created in a given disk group, but users are forced to use the same RAID level for all the volumes.
An overview of the various setup options and other available features in the firmware are provided in the gallery below.

UPDATE: After looking carefully over these screenshots - I think their review might be SERIOUSLY lacking... I see a RAID 6 option in the setup for the box. But it's greyed out. Probably because they didn't have any drives in it when they were there is my guess. need 4-5 drives MINIMUM to do it to start. But with this many drives, Even testing a RAID 5 is just honestly a bit stupid. It should have been tested RAID 6 and in that situation, might actually be a more attractive option if it is capable and performs.But then again, RAID 5 generally is faster then RAID 6 due to the added calculations for the extra parity.. And it's RAID 5 performance was pretty weak unless I'm reading the numbers wrong. That is, if the RAID 6 is actually activatable within this device and not just an option within their software that is disabled in this device all together. But I would have thought this review would have tested that mode since that is what an 8-drive setup should have been setup for.

The benchmarks were done with all 8-bays filled with WD RE Drives in RAID 5.The screenshots show that we can have disk groups. So, for example, you could allocate 4 disks to one disk group and run a RAID 5 volume on it. Then, the other 4 disks could be in another group and you could run a RAID 6 volume in that group.
What is the problem with performance that you are seeing? These Atom-based NAS units basically saturate the network link (accounting for overheads). Remember two links teamed is 2 Gbps in this case and that translates to a maximum of 250 MBps. Accounting for overhead, I see units saturate between 210 - 230 MBps and never have had any unit go above that unless I am teaming 4 ports or more (as you can see in our QNAP TS-EC1279U-RP review)
I will take your feedback about RAID-6 evaluation into consideration in the next round of benchmarks.

How is single client, 1.5 MB/s throughput at about 100 ms latency "stellar?" That sounds absolutely abysmal to me. I'm curious to know how you set up IOMeter... I'd like to repeat the test on my own box and see how it fares.mitchdbx - Saturday, June 15, 2013 - link
There comes a time in your life where you just want things to work without the hassle of them breaking every time you turn around. I OWN the 5bay unit (for over a year now) and can say that the UX is wonderful on these. They configure to let you know when something goes wrong (send email, beep, send SMS, etc) so you can fix the issue. Please look at the product before you make conclusions that they are only "dumb" boxes. You can run Plex, and Many other media servers in addition to a DNS, DHCP, Web server with PHP and various CMS installs. Photo Management, Surveillance, etc....On another note, a inexperienced individual commented that an issue will arise when a drive fails and the array must rebuild. If you are using quality drives and constantly spinning the drives, the chance of a two drive failure is very low. As anyone that has years of experience with computers, keep the drives spinning and things will be fine, it is when you shut down and start up that issues come into play.

More FYI about the RAID levels....http://forum.synology.com/wiki/index.php/What_is_S...

Synology aren't using some "nonstandard raid" with SHR. They are using mdadmThis is how to restore an array in standard PC using linux if your DiskStation would fail:

I'd say that's even better than using some H/W Raid controller. Good luck replacing one of those with something else than an identical controller with the very same firmware etc.

Wow great timing! Been looking for a NAS with huge storage capabilities to transfer data offsite. Haven't seen many around... Buffalo Terastation looks good but I haven't seen reviews for those or any other modern NAS systems. Thanks for the review!SirGCal - Thursday, June 13, 2013 - link
Did I miss it? But I didn't see it support Raid 6? But Raid 5, ESPECIALLY with large drives, is just asking for failure. I personally have one 8-drive array, building my 2nd now. First with 2TB drives, new one with 4TB drives. Both are Raid 6. Old one 12TB, new one will be 24TB. Ya you lose 2 drives of usable space but that creates 3-drive failure protection. Or basically, when a drive fails and you're rebuilding, you have protection from another drive failing. Cause THAT is what it will happen...But I didn't see anything in the whole thing about Raid 6 at all. I would Never build an 8-drive system with Raid 5... Not especially with consumer grade hardware... Without Raid 6... It's just not worth it for large array...

No, it only creates 2-drive failure protection. Lose 3 drives in RAID6, and you're toast.SirGCal - Friday, June 14, 2013 - link
3-drive failure, as it it takes 3 to kill the array.. Point is you can be repairing one, if another one fails, your not dead yet... As you would be with RAID 5...
