Miscellaneous Factors and Final Words
The Synology DS1812+ is a 8-bay NAS, and there are many applicable disk configurations (JBOD / RAID-0 / RAID-1 / RAID-5 / RAID-6). Most users looking for a balance between performance and redundancy are going to choose RAID-5. Hence, we performed all our expansion / rebuild duration testing as well as power consumption recording with the unit configured in RAID-5 mode. The disks used for benchmarking (Western Digital WD4000FYYZ) were also used in this section. The table below presents the average power consumption of the unit as well as time taken for various RAID-related activities.
| Synology DS1812+ RAID Expansion and Rebuild / Power Consumption | ||
| Activity | Duration | Avg. Power Consumption |
| 4TB Single Disk Initialization in RAID-0 | 10h 23m 40s | 32.59 W |
| 4TB RAID-0 to 4TB RAID-1 (Expand from 1 to 2 Disks) | 9h 26m 7s | 42.83 W |
| 4TB RAID-1 to 8TB RAID-5 (Expand from 2 to 3 Disks) | 34h 32m 9s | 51.85 W |
| 8TB RAID-5 to 12TB RAID-5 (Expand from 3 to 4 Disks) | 27h 18m 58s | 64.15 W |
| 12TB RAID-5 to 16TB RAID-5 (Expand from 4 to 5 Disks) | 29h 41m 29s | 74.12 W |
| 16TB RAID-5 to 20TB RAID-5 (Expand from 5 to 6 Disks) | 32h 39m 26s | 83.88 W |
| 20TB RAID-5 to 24TB RAID-5 (Expand from 6 to 7 Disks) | 35h 51m 29s | 92.79 W |
| 24TB RAID-5 to 28TB RAID-5 (Expand from 7 to 8 Disks) | 38h 42m 13s | 101.93 W |
| 28TB RAID-5 Rebuild (Replace 1 of 8 Disks) | 35h 28m 14s | 102.42 W |
Due to the nature of the CPU, RAID expansion / rebuild takes progressively longer as the number of disks increase. Coming to the business end of the review, the Synology DS1812+ has plenty of positives (applicable to other Synology units that I have evaluated also): It is simply the most reliable NAS that I have encountered. All RAID expansions and rebuilds complete without issues, performance is solid and consistent, and the DSM interface is a joy to use. I haven't even touched upon the breadth of apps available which extend the functionality of the NAS beyond the basic firmware features. The combination of stability, price and expandability (coupled with extensive virtualization support) makes it ideal for many small scale virtualization setups. The number of bays available also makes it possible to create multiple disk groups and run volumes with different RAID levels on the same unit (each disk group can have multiple volumes, but all of them have to be of the same RAID level). The DS1813+ carries forward the DS1812+ with the addition of two more GbE network ports (Synology plans to sell both models in parallel).
Despite our extensive praise for the DS1812+, we feel that Synology has left open some areas for improvement. From the hardware perspective, I would have been happy if they managed to provide a AES-NI enabled platform at the same price point. A USB port or two on the front side of the chassis would have been nice. From the firmware side, it would be good to have support for volume encryption in addition to folder encryption. In addition, it would be interesting to see if provision can be made for dynamically expandable volumes with the ability for a disk to be part of multiple volumes (possibly in different RAID levels). This would make the Synology NAS units even more appealing to the crowd currently using WHS / Windows Storage Spaces.
In closing, Synology manages to hit yet another home run in the 8-bay SMB / SOHO NAS space. They are miles ahead of the competition in almost all respects. Even the few quibbles that we outlined in the previous paragraph are just aspects which might make it even more difficult for competitors to catch up.

OK, while you're pulling your many TB down from whatever backup service over your internet connection, also killing your internet pipe, slowing it down for everyone in the process for likely weeks or months to get the pull unless your one of the few on fiber or FIOS, I'd rather not have to repopulate 24-28TB of data from backup in the first place. Good luck with that. While I do keep a backup, it's far better not to need it.Jeff7181 - Tuesday, June 18, 2013 - link
Who sad anything about "cloud" backup? Buy additional high capacity drives and only spin them to perform backups.SirGCal - Sunday, June 16, 2013 - link
UPDATE ON SYNOLOGY:We were finally able to get the Subsonic module loaded and working on it properly and it works fine for music... mostly. But it doesn't have the horsepower to transcode bluray content, even just one viewing, on the fly. I don't know if it's memory or CPU or both but even over the local network (which is disgustingly overkill) it just can't do it. Choppy, stutters, etc. where as mine is smooth and uses ~ 10% CPU or less. I wouldn't think it was that hard on the CPU but... We're still trying to get this to work as it is one of the requirements for him to keep/use this box.

Forgive me if this is a stupid question, but what's the reason for USB and eSATA ports on a box like this? I understand the basic point of a NAS (as a single box where I can dump a buncha drives and have the HW provide some level of RAID) but how do the USB/eSATA ports play into this?Is the idea that, after I have filled this thing up with 8 internal drives but I need still more space, I start adding drives via the external ports?

There are ways to extend the array, but honestly it becomes a point where the most reliable way becomes to buy or build another array. Doing it as a server in box, you can do 8/12/16/24 drive configurations... This stand alone is the first 8 box setup I've seen aside from rack servers which obviously are true rigs costing a LOT more.name99 - Friday, June 14, 2013 - link
You don't need to convince me. I've built my storage around 5-yr old Macs connected to a bunch of 5-yr old drives using Apple RAID and AFP. Maybe not the right solution for everyone, but meets my needs, and basically free.But that's not the point. My question remains. For the people who ARE the target for this sort of device, what's the point of the USB/eSATA parts. Our reviewer, for example, wanted USB ports in front of the box. Why? What would he do with them?

Sorry, According to their own site, you can use two of their own Synology DS513s to increase the capacity to 18 drives. However 18 drives even as RAID 6 becomes not so hot. 8-12 drives is about my limit. At 16 I make two RAID groups and then one volume for the virtual array cluster to use the data from. Then you have 4 parity drives but much better drive protection crossed the array instead of just 2 drives of parity. That's another discussion though. They sell bigger boxes though that I think actually do this type of configurations though. I'd have to research it though. But even their reported numbers don't show great performance. Still should be OK for most home use.If you want to plug in a single drive and just add it as a shared folder, I think it will do that. I can ask my friend to give it a go if he gets home and see if ya like.

I think I have a feeling now, from what both you and Ganesh have said.Seems a strangely limited market, to have an environment that wants so much storage, but no-one is willing to just use one of the machines around to plug a drive into and have it act as a file server. But, I guess, I'm not the target audience.

Ya, that's the catch. For what it is, it's not bad. But the biggest problem in my eyes is that's all it is. It can't do the "other" things that a server could do such as run the other software packages that my servers do... Or at least we haven't figured out how to make it do so yet. We've been beating the pants off my friends rig trying to make it run something like Subsonic which is a media streaming service to stream your own media files to your self when your offsite. Music and videos... I love it and he was hoping to use it also but isn't getting his Synology box to run anything this complicated yet. In some ways I'm actually a bit surprised since it's just a java daemon. (in windows it's a service). I thought of all my software tools, this one might actually work. And there might be a way, we haven't tried hard yet. Or the other fear is the actual CPU won't be capable of trans-coding on the fly... at least videos. We're pretty sure the software will install, but the Atom's are pretty weak. We'll see.. Worst case I guess, we setup yet another server to feed off it for the streaming. Sort-of defeats the purpose but... If it can't do it...Micke O - Monday, June 17, 2013 - link
The drives in each DS513 must be it's own volume. No BIG volume with all the drives in the main unit and the expansion units is possible.
