Single Client Performance - CIFS & iSCSI on Windows
The single client CIFS and iSCSI performance of the Synology DS415+ 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 DS415+ manages to compare favorably against the ARM-based solutions, obviously. The real tussle in these single client scenarios is not against the other Rangeley NAS (Seagate NAS Pro), but against the QNAP TS-451 based on Bay Trail-D. Both DSM and QTS are mature operating systems. The higher core count in the DS415+'s Atom C2358 compared to the TS-451's Celeron J1800 probably help the former edge ahead in most of the benchmarks presented in the graphs 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.

Does this (or any NAS that you know of) support simultaneous access from both the USB port as well as over the network? I understand the "only one interface can control the storage at one time" issue, but I'm really hoping someone is working to overcome this, even if it means that one of those interfaces is locked into read-only mode.ganeshts - Thursday, October 30, 2014 - link
The USB ports are host ports, i.e, storage devices or WLAN USB sticks can be connected to it. The USB port can't be used to connect to a PC for using the unit as a DAS (direct-attached storage).rpg1966 - Thursday, October 30, 2014 - link
Seriously, articles with graphs showing two aspects of the same thing (e.g. rebuild times in this case) need to be shown on an X-Y chart, so that the trade-offs are immediately and obviously visible.The same goes for many similar pairs of charts you show in other reviews, e.g. power-vs-noise in GPU or case reviews.

I almost spat coffee all over my monitor when I saw the tertiary drive in the test rig. That is a very expensive way of eliminating the test rig as a performance bottleneck in the tests.Salipander - Thursday, October 30, 2014 - link
It's about time that transcoding includes h265 support, and be mentioned in reviews. This DS415+ unit may provide this for resolutions up to 1080p. This is for sure not supported by the DS415play, as it won't have the cpu power to do this in sw, but the DS415+ just may do it.I have quite a movie collection and I am halving the needed storage by transcoding the files from h264 to h265, including all the sub 4k files (which is 100% of them ;-) I may be an early h265 adopter, but the cpu intensive transcoding is worth the effort already. The x265 coder is of such a good quality now (since august at least), that I dare to go for it.
It would be nice to have the DS Video capability to transcode h265 to something suited for current tablets and media players!

Is the ram soldered to the PCB, or in a dimm that could be swapped out for an ECC module?skarnm2 - Thursday, October 30, 2014 - link
I did read elsewhere it was soldered. It is on the larger models it's swap-able.chubbypanda - Thursday, October 30, 2014 - link
Non-ECC and ECC modules aren't interchangeable. Do not attempt!mpbrede - Thursday, October 30, 2014 - link
Define COTS, please? Some form of "... Off The Shelf"ganeshts - Thursday, October 30, 2014 - link
Commercial :)I thought it was pretty common usage, and a cursory search online makes me think I may not have been mistaken: http://en.wikipedia.org/wiki/COTS
