Multi-Client Performance - CIFS
We put the Synology DS1812+ through some IOMeter tests with a CIFS share being accessed from up to 25 VMs simultaneously. The following four graphs show the total available bandwidth and the average response time while being subject to different types of workloads through IOMeter. IOMeter also reports various other metrics of interest such as maximum response time, read and write IOPS, separate read and write bandwidth figures etc. Some of the random access benchmarks don't fit in the graphs below. The scales were not altered in order to make the comparison against other NAS units (which fit in the scale) easier. Readers interested in the actual values can refer to our evaluation metrics table available here.
Bandwidth and response times can be compared against NAS units from other vendors based on the same platform (Atom D2700). One thing to keep in mind when analyzing the results above is that the LaCie 5big Pro is a 5-bay unit and the Thecus N4800 is a 4-bay unit, while the DS1812+ is a 8-bay. Sequential performance doesn't seem to reach that of the competitors, but the DS1812+ is stellar in the real life tests / random accesses (again, it is necessary to remember that the units have different number of hard drives being accessed during the test).

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.
