Synology DS1815+ 8-bay Intel Rangeley SMB NAS Review
by Ganesh T S on November 18, 2014 6:30 AM ESTSingle Client Performance - CIFS & iSCSI on Windows
The single client CIFS and iSCSI performance of the Synology DS1815+ was evaluated on the Windows platforms using Intel NASPT and our standard robocopy benchmark. This was run from one of the virtual machines in our NAS testbed. All data for the robocopy benchmark on the client side was put in a RAM disk (created using OSFMount) to ensure that the client's storage system shortcomings wouldn't affect the benchmark results. It must be noted that all the shares / iSCSI LUNs are created in a RAID-5 volume. The DS1815+ manages to compare favorably against the two other 8-bay solutions we have evaluated before. The benchmark numbers are provided in the graph below.
We created a 250 GB iSCSI LUN / target and mapped it on to a Windows VM in our testbed. The same NASPT benchmarks were run and the results are presented below. The observations we had in the CIFS subsection above hold true here too.
These numbers are only to be expected - the Seagate R8 is based on the Celeron G1610T, a 2C/2T processor running at a lower frequency (compared to the 4C/4T solution in the DS1815+). In addition, DSM is much more mature compared to Seagate's NAS OS back when the R8 was reviewed. The DS1812+, on the other hand, is a Atom D2700 NAS. Evaluation was done with a older version of DSM and, obviously, the newer hardware brings better performance.

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
