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).

    Thanks for that feedback. I did a search for 2411 and 1512 but they seem to be 'past tense' models for Synology. But what I did find is there are 8-bay and 12-bay models it seems. I think this goes way beyond my needs and perhaps even data growth. Perhaps a 4-bay or 5-bay might be more suitable for me in terms of growth and capacity. And then, to have a double NAS of the same time where one is main and the other fall back, or, a backup to the main.

    Currently I am not doing RAID on my 2-bay DS213. I just do each disk as independent volumes and then back those up over USB3 to an external box housing two more matching drives. Simple but it works.

    The draw for me was the HDMI port on the QNAP NAS whereby I could also have the NAS double over as a HTPC Media Server as well. I hear that Synology is suppose to release a DS714 that also has HDMI, and supposedly in June. But, they have been completely mute about any information on the product. But on the other hand, perhaps I should not let HDMI port be a deciding factor as to which NAS I do buy.

    Thanks for the input.

    How does it deal with silent corruption? What happens if you yank the power-cord during a write? How do I get my data off the disks if the NAS dies?

    God forbid a NAS review ever tell me any of these things.

    why is there still not integration of 10Gbps ethernet interface in these storage/networking products.
