Synology DS1815+ 8-bay Intel Rangeley SMB NAS Review
by Ganesh T S on November 18, 2014 6:30 AM ESTMulti-Client Performance - CIFS on Windows
We put the Synology DS1815+ 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. The tool 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 interesting aspects from our IOMeter benchmarking run can be found here.
At the outset, it must be said that the two extra network ports on the DS1815+ (compared to the Seagate R8 and the DS1812+) make an apples-to-apples comparison difficult. In sequential workloads, the extra bandwidth delivers better throughput numbers. Average response times are also much better for the DS1815+. However, in the real-life and random 8K workloads, the performance of the DS1815+ and DS1812+ don't show much difference. The Seagate R8 also manages to deliver better results in a number of scenarios for this workload. That said, the average response times are excellent and the maximum response times are kept well under control.

I actually own the DS1812+. I was going to build my own NAS but I wanted a hardware solution for the RAID, because software RAID is just too slow. Then I could not find the right type of tower I wanted for the drives, that was another issue, then I was not able to expand the RAID on the fly if I wanted to add more drives or even build a dynamic partition, so I decided to go with that solution instead. I haven't got one single problem with my unit that just reached 1 year now.There are far better solution in NAS but their price is extremely expensive, starting at 50K like the Equal Logics. This solution is for SMB or people like me that don't want to spend time on assembling parts for a NAS. Also for a good NAS with good parts might cost more money: just the RAID card in hardware (PERC 6 or 7) is $300 and some NAS run with Xeons procs.

I have read the reviews about the Synology NAS devices with Avoton CPUs (DS1815+ and DS415+). Having bought one now myself, I wonder how far they have been tested.I got the impression from former Anandtech articles about the new Avoton CPUs, that NAS devices equipped with those should be able to encrypt data with virtually no performance impact. The reviews proved that point, so I bought one.
However, Synology offers only eCryptFS, which does not work via NFS and exhibits the file names and directory structures in the clear - also, the maximum filename lengths are truncated to 143 characters. Thus, using it for general backup purposes is somewhat pointless.
On a side note, it is a shame that the Synology kernel configuration does not even include the dm-crypt.ko and cryptoloop.ko modules and that there are no userspace cryptsetup or losetup executables. This limits the usefulness of the Synology Avoton line of products to almost zilch.
Also, the GPL sources under http://sourceforge.net/projects/dsgpl are out of date. There is no 5.1 version, which would contain the neccessary tools for the new Avoton machines like the DS1815+ and the DS415+. Thus, there is no self-cure for the situation, either.
This is the kind of improvement hints I have grown accustomed to in Anandtech reviews, but no word of it in the final words of these ones.

"Bay Trail is proving very effective in tablets"Seriously? Proof ...
Being used for such well known brands as Teclast and Onda and Voyo is not "proving very effective".
Intel's goal for 2014 was 40 million tablets. I'm guessing, since we haven't heard much since that goal was set (but we have heard about the 2014 billion dollar losses in their mobile division, complementing the 2013 billion dollar losses) that they didn't QUITE make that...
The Foxconn (oops, sorry, "Nokia") iPad mini clone MAY change that --- but that won't ship for another three months, and I expect Apple have a plan in the wings the moment they feel any pressure at the low-end to drop the A5 iPad mini, move the iPad mini 2 down to that price slot, and, if necessary, slide in an A8 based iPaid mini 4 at the high end...
Meanwhile Lenovo was so impressed with Bay Trail that they dropped it from the Yoga for the (much more expensive) Broadwell-Y, not that that has done them any good...

I recently search for a NAS and find this category is actually the most overpriced stuffs in the consumer market nowadays. There are not much hard technology needed to build one and the actual cost is not expensive. And I don't see much power saving compare to a dedicated computer with RAID, and this is not quiet at all. The only possible reason that this high price tag existed is there are not many players (yet) on the market.I would suggested waiting one more year and see what happens. Compared to this, even Macs or iPhone are not overpriced at all...agodzilla - Friday, August 19, 2016 - link
Synology DS1815+ only SATA / 1.5 Gbps speed will be newsin the spec DS1815+ have sata2 * 8
but slot 7 and slot 8 can't over the 1.5 Gbps (SATA1)
even SSD still can't over the 1.5 Gbps (150MB/s)
they not tell this problem before consumer buy it,is illegal in your country?
if the consumer know slot 7 and slot 8 can't over the 1.5 Gbps,they maybe not buy this product
this is our test video https://youtu.be/YDyEZKT_nAQ
you can confirm by yourself ,if you have DS1815+
and DS1813+ same problem ,is so many years
this will be big news,make Synology say sorry and compensate
