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.

AES-NI support would be a great addition for a real SMB NAS...even SMB's should be concerned with security. What are the chances NAS manufacturers will come out with devices based on AMD Kabini? AMD does a lot less feature segmentation in their chips and Kabini has AES-NI so it seems like a better solution until Intel matches that with Atoms (low TDP Haswells will be too expensive.)JDG1980 - Thursday, June 13, 2013 - link
The two features I look for in off-the-shelf NASes are ECC RAM, and the ZFS file system. Unfortunately, it seems that none so far have saw fit to include them.pwr4wrd - Friday, June 14, 2013 - link
I completely agree with you, Even for home/SOHO use, what good is a NAS unit if you dont have data integrity.Samus - Saturday, June 15, 2013 - link
This will change with the Atom family supporting ECC. I don't know of any real advantages ZFS has over ext4 for home/soho.phoenix_rizzen - Monday, June 17, 2013 - link
Instantaneous near-unlimited number of snapshots, end-to-end checksums, integrated raid features without requiring RAID controllers, integrated volume management, storage pooling, etc, etc, etc.Once you get beyond 1 harddrive, using anything other than ZFS (or other pooled storage system) is heavenly. There's just no comparison to ext*+LVM.

I wonder how multi-user performance would scale if it had a 10 Gbps uplink to a 1 Gbps access switch. Maybe I'm out of touch with arrays of this size, but those numbers seem low for an 8-disk array. Maybe it has to do with the Atom CPU? Maybe the RAID controller has no cache? Honestly I'd be highly disappointed if I spent $1000 on the chassis and another $1000-2000 on hard drives and could barely reach 1 Gbps under the best circumstances.DigitalFreak - Thursday, June 13, 2013 - link
There is no RAID controller. The SATA ports are either off of the Intel embedded ports, or more likely off of a 3rd party controller.SirGCal - Thursday, June 13, 2013 - link
Try again, They used 8x WD4000FYYZ, They run $410 each... If you get a deal on them. Upwards of $500 if you go to a brick and mortar store... at 400 each, that's $3200 just for the drives for their enterprise class drives for this test. Most people aren't going to use them.Gigaplex - Thursday, June 13, 2013 - link
That just backs up their point even more. Spending $1k-2k instead isn't likely to get you faster drives.SirGCal - Friday, June 14, 2013 - link
No, you missed my other point... The 8-drive RAID 5 is a failure waiting to happen, enterprise class or not. When a drive does fail, you'll have to repair it. During that 38+ hours... That is the MOST likely time (also when all the drives are old, warn, and getting their tails kicked in doing massively hard reads) that another one is going to fail... Then you lose the entire array and all of your data. That was the point I was trying to make.
