I ordered the 2016 Synology four bay DS916+ 8GB yesterday along with 4x WD Red Pro 6TB. Hoping to see some huge numbers in the like box of TS post above 
Link to a (for me) very interesting post about ‘unofficial’ HW accel enabled [root] transcode for DS216+ (That’s 916+ little brother/previous year CPU; Celeron N3050 dual core [Celeron N3060 dual core is in this year DS216+II - compared to Pentium N3710 quad in the 916+) forums.plex.tv/discussion/comment/1217006/#Comment_1217006
And the mandatory spec sheet link

Storage Review (2 GB version, unfortunately no Plex testing) here in case someone is interested.
edit: I would happily pay (some kind of reasonable amount) to help out making HW accelerated transcoding happen. [-O< Anyone else feel the same?
edit2: Techpowerup review (7/28) here. 2 or 8 GM memory version? It’s not mentioned in the text/specifications (but their box shots clearly shows 8GB). At page 11 there is a small test of direct play using Plex:
Techpowerup review:
! We initially tried a 24 Mbps media (bird24.mkv) file, which was reproduced just fine. This raised our interest and we increased the bar with the 34 Mbps version of the same media file, which the server’s hardware managed just fine. To cut a long story short, we were able to stream up to 55 Mbps media files to our devices; however, such high bitrate streaming took some time to initialize. We even tried 4K media (NASA: Thermonuclear Art), which produced a delay of around 20-25 seconds at the start but was reproduced without frame drops and pauses afterward. The only problem was the very slow seek function. In general, Plex’s performance was pretty good. We were prepared for very daunting results since Plex doesn’t exploit the transcoding capabilities of the Intel N3710 CPU, but that was thankfully not the case.
edit3: This is interesting, thanks @rtfmoz! (link to thread)
@rtfmoz said (my markdown):
I’ve had a talk with Synology about opening up hardware transcoding on their platform to Plex. This was their response.
“Regarding hardware transcoding through Plex, we have actually been communicating with Plex for a long time about whether they can implement this. However, it might be because Plex supports too many types of devices and it’ll take up a lot of their resources to optimise the software for each device (I’m not 100% sure), this just hasn’t happened yet. There are other third-part app that has utilised hardware trascoding on Synology NAS, so we are not hiding the secret from anyone, especially not Plex.”
The DS415+, the new DS916+ support hardware offloading of transcoding tasks on the NAS. To give you some idea of the benefits, currently doing a low bandwidth 1080p transcode on the 916+ uses about %90 CPU. The same video in the Synology video station uses %30 CPU. This is a massive difference in performance.
There literally a hundred thousand people who would benefit from having this feature supported in Plex. I realise it may not be a road you want to travel but if you change your mind. Please let Synology be your testing platform. I for one would only be too happy to use my DS415+ as a test platform for code. I am chasing up Synology for more information on how to utilise the hardware in the current version of disk station manager (DSM). In fact I signed up to PlexPass just so I could make this post. I have been looking closely at the PMS early releases and hope that one day we will see a feature like this pop up for testing.
Fingers Crossed.
