Thanks for the info. I do remember buying additional RAM at time of purchase, but it's only reporting 6144Mb total physical memory from CP now. Even while streaming, recording cameras etc however I am seeing usage at 31%.
I've got an i5 NUC with SSD here already that was running ubuntu and handling Plex. I think it performed the job much better than Synology, however it crashed and I couldn't be bothered going through the install and setup process again, so reverted back to Plex Server on Synology.
I think a 2 or 3RU server might be the way to go long term though. I've certainly got the space to go even bigger if it means it's more affordable.
Thanks for your advice guys. (really need to install the thumbs up smiley)
Have you upgraded the ram in the Synology? You can upgrade it to a total of 16gb this might be able to help with that. This is certainly the cheapest option.
Alternatively you could use a NUC to run the Roon server (accessing the drives on the Synology) and the Synology to run the plex and camera recording. This way you separate the CPU power across both devices.
Easiest way to have a NUC in your rack is use a rack shelf (I have a 1RU one here I am not using you can have for the cost of postage), you'd have to run a HDMI cable to an available screen. You'll have plenty of room to do this now you only have one switch.
With all that said and done if you wanted an all in one solution, you can absolutely build a quiet 2RU server (I think you may even be able to jamb a 3RU one in there) you'll just need to use the right components and build it yourself.
You wouldn't be able to use an off the shelf server as these are dreadfully loud, but these days you can almost get away fanless for a quad core system. If you go down this path I'm more than happy to steer you in the right direction.
Hopefully you can get a partial or full refund on this.
If not and you need to attempt a repair yourself, here is the service manual and links to a parts supplier;
Well with the exception of watching remotely from a laptop while traveling last week, it's always streaming in original format. I can't think of any reason or application where I would need to transcode honestly.
The Synology has not failed me yet. The exception has been streaming 24/192 or higher resolution audio from Roon Server (also running on NAS), but I narrowed that down to 6 x IP cameras recording to the NAS in high resolution and high frame rates. I assume it was consuming all the available bandwidth.
I'd much prefer to have a dedicated 2RU Server, however the rack is in my home office and I really don't want the associated noise while I work all day long (unless there's an ultra-quiet option).
