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.

Happy with raid 5 on a 4 bay NAS but I still watch carefully.The problem is simple. I, like most people, if buying an 8 bay NAS would buy all the disks at the same time so there is a high chance the disks are all from the same manufacture batch. So if one disk in a batch fails there is a higher chance of another failing soon after - I know because it has happened to me.
So for 8 disk NAS Raid 6 is a key feature.
That still gives me a 24TB array. Say 16-18 Gb per lossless blu-ray rip leaves room for 1200 blu rays movies (or 4000 if you are happy with some compression) and about 2000 episodes of TV epsiodes at standard definition (no compression) and maybe 3000 CDs.
That should be enough!

My point exactly!JeffFlanagan - Friday, June 14, 2013 - link
Don't get all your drives from one source or vendor. Buy an assortment of drives for your array, and you'll be much less likely to have 2 drives fail at once.brennok - Friday, June 14, 2013 - link
I guess I am not like most people. I used SHR2 so I could fill it with various disks as I upgraded. I only started with four 1TB Reds.SirGCal - Friday, June 14, 2013 - link
But that's never enough, building my 2nd 24TB rig now actually.. :-/ But I refuse to compress my BRs. I do strip out everything but the movies, but I also do NOT pirate them. I buy them and put them on my server. No one gets them either. Being in a wheelchair, it's one of my few hobbies though so I have a LOT of movies...cjs150 - Monday, June 17, 2013 - link
Apart from the wheelchair part I do exactly as SirGCal. Using a standard Blu-ray rip (at high quality rather than original) a 2 hour movie comes in at about 15Gb file. Some are a bit larger (17Gb), some a bit smaller (13.5Gb is the smallest).That chews up a 6TB rig very quickly - particular as 6TB hard disk space is not 6TB because HD manufacturers do not quote HD space in binary but decimal units (the difference is about 7% per TB)..
I look forward to when HD come in 10TB sizes! That would be enough on my 4 bay QNAP 419+ which I consider to be an ideal consumer box - plug it in and it works

Can someone explain to me why this would be better than making your own NAS (with FreeNAS or something similar)? Correct me if I'm wrong but you should be able to put together a nice PC for NAS purposes for under $400 without a RAID card.... $800 (give or take) with a raid card that should be better then this no?Peroxyde - Friday, June 14, 2013 - link
Exactly! You'd even be agreeably surprise that ZFS is better than a RAID card. Additionnaly your own build server will have much more RAM. I was about to buy a QNAP 4 bays. But after spending sometimes to read more about NAS4Free, I realize that a "roll you own" NAS server beats the prebuilts on all performance factors: better case, silence, better CPU, RAM, etc. etc. There is a big inconvenience though, you need to learn NAS4Free (or FreeNAS. the commercial implementation).Case in point: my NAS server costs me less than $400 (I have the luxury to wait for quality parts to go one sale): Fractal Design R4, Corsair VX 550, 8GB G-SKill Snipper DDR 1600. Just waiting for a good mobo + AMD low power CPU and I am ready.

Not necessarily better or worse. I was looking to replace my WHS and I didn't feel like doing another build. I wanted something compact, quiet, and efficient since it stays on 24/7. The Synology came highly recommended and I didn't feel like doing test builds to figure out which OS I wanted to use.SirGCal - Friday, June 14, 2013 - link
See my reply above to a few posts. I just put it up a few minutes ago... It IS better.. And quite a bit cheaper. The Synology stuff really is NOT very good for the savvy. In-fact, ESPECIALLY with this many drives, your data is at too much risk... I tried to explain it in detail. Sorry for the rather long windedness of the post but I try to be detailed.
