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.

Yes, you can add the DX510 expansion chassis via the eSATA ports and get a total of (5 + 5) 10 more bays. That is why you have the 18 in the DS1812+ :)Peroxyde - Friday, June 14, 2013 - link
@name99 the USB/eSATA ports allow to make a backup of the NAS on external drives or may be dump content on your NAS. They are not to extend the capacity of your NAS.name99 - Friday, June 14, 2013 - link
OK. Thanks.Again to me seems a strange use case which can easily be duplicated just by uing one of the client machines, but I guess when you're selling something costing a $K you try to add in any random thing you can think of to make it appear worth the money.

Your NFS numbers seem way too low compared to the CIFS numbers. Might want to drop the 'tcp' from the options, is the most likely culprit. NFS defaults to udp, not sure why you're changing that.ganeshts - Friday, June 14, 2013 - link
I see a number of vociferous comments about how a ZFS build / building your own NAS will offer better performance and how Synology (or, for that matter, any other vendor's off-the-shelf NAS offering) is just too costly. Let me try to address the issue:1. Building your own NAS with a configuration tuned to what you require will obviously be more cost effective and efficient - no doubts about that. Synology and other such solutions are targeted towards SMB / SOHO users who don't have the expertise to build a NAS on their own, or feel that their time is better spent buying a off-the-shelf ready-to-use offering from a vendor. Maybe the IT admin of the SMB has better things to do than sitting down and building a PC and installing the appropriate OS etc. These off-the-shelf NAS units are just plug and play.
2. Expandability: Units such as the DS1812+ offer the ability to extend the number of bays by providing support for extension units (DX510 has 5 bays and you can attach two of them to the unit). Plug them in and you have a total of 18-bays. Try adding that to your own build (first, you have to make sure the eSATA port you connect the new bays support port multipliers, then you have to spend a lot of time reconfiguring your host OS to recognize and add the new drives in the new bays to your existing array -- these are not impossible things, but just suck up a lot of time)
3. Features : NAS vendors offer 'app stores' to extend the feature set. For example, I am currently trying out Surveillance Station on the DS1812+ right now. Ready-to-use minutes after installing it. On your PC, you have to set up something like iSpy and spend time making sure it is compatible with all your equipment. Synology becomes a one-stop-shop for such features.
In summary, yes, if you are tech savvy and have a lot of time at your disposal, you are better off building your own NAS. There is plenty of open source software available to enable such systems (and to be fair, we are working towards evaluating a custom-built NAS for some time). We elect to do extended coverage of NAS units such as the DS1812+ and QNAP TS-EC1279U-RP because a large number of readers are IT admins / IT decision making people at many SMB / SOHO firms, and they are looking for off-the-shelf solutions. The off-the-shelf NAS market is pretty huge, and that is why you have a large number of vendors doing quite well with increasing revnue.. QNAP, Synology, Thecus, Netgear, Iomega / LenovoEMC, Asustor... The list is pretty big..

Thank you for bringing some sense to this one sided thread. Building your own NAS can be done at a lower cost and offer you great benefits. However you will be hard pressed to build something more refined then this unit especially in regards to size and ease of use.bsd228 - Friday, June 14, 2013 - link
The simplest form - an HP Microserver + Freenas is pretty easy to assemble. Allows for ECC memory and up to 16gb of it too for higher performance. Still is a tiny form factor, low power, low noise. If expandability is the driver, large PC cases and motherboards with PCIX cards will always win. If features matter, a linux install offers faster development and many more.I combine them all together - Microserver with 16gb, an SSD for caching, solaris (full install) with virtualbox, Ubuntu in a VM. It's still a lightweight processor (I'd prefer one of the ULV ivy or haswells), but it kills an Atom.
Companies are flocking to this market because it offers nice margins...like the markup Puget might put on their beautiful systems.

The Microserver is a great build your own NAS box but it does not stand up to the DS1812+. For one you can only hold 5 3.5" disk max, while the Synology can hold eight and they are all hot swappable. How about warranty/support anyone?My opinion is based on owning both types of systems. I just sold my 1511+ + DX510 and I own a OI + Nappit ZFS array. They both have pros and cons. You can almost look at it like a person who's looking to buy a Mac verses a computer nerd who builds all of his boxes. There is a reason why Apple is in business and it's similar to why the Synology, QNAP's and Netgear's are able to sell NAS's.

Madhelp - the Microserver trivially takes 6 drives and has the PCIX slots to take more externally if you really wanted and needed the capacity. Or you could just buy two of them - with memory and a second NIC they're still only 400 each, compared to the $999 price of this unit bare. Either way, the DS1812+ can't stand up to the cpu, the features offered by zfs, the memory capacity, the overall feature set. And you can certainly get support for the software (not freenas, but WHS, or Nextenta or Solaris, others, and have the usual year warranty for the hardware.Synology and the others combine decent software, easy of use for a limited feature set, and barely good enough hardware into a package. IOW, one out of 3.

6 hot swappable drives? I don't think so. WHS is discontinued and all of those other Solaris based products you listed cost thousands of dollars to buy and support. You might get more CPU and the ability to add more ram to a Microserver box but whats the result? For a storage box it's still going to be slower then a DS1812+ in regards to throughput. In fact while the reviewer dismiss the new DS1813+ it now can deliver 350MB/s reads and 200MB/s writes to the network. I've never see anything close to that from a Microserver, point being its in another class. You guys might complain about the cost but you get what you pay for.
