I am presently running Roon Core on a fanless NUC with Rock installed which is great.
Prior to the NUC Roon Server as running on my Synology DS218+ but performance was not acceptable.
My music library consists of about 90k tracks, most of them lossless files (FLAC) but hardly any HiRes files „better“ than 96/24.
I am using Roons downsampling options in one room when streaming to my vintage stereo system with a DAC capable of max 48/16.
I intend to use room correction feastures in the future.
After having read in another thread that Roon Server running on a DS720+ is working very well I am to give Roon Server on a Synology another try:
I am planning to upgrade to a DS72x+ model in any case and just wondering which version might be better for running Roon Server:
has a significantly faster CPU (no Intel anymore) but no GPU on board anymore
allows RAM of upto 32GB
will be served longer by Synology as the 720+ which was introduced in summer 2020
The price differential here in Germany is less than 100 Euro so not too significant.
So I am wondering which NAS would give the better performance as a Roon Core?
my 720+ (replacement for my trusted 716+ that had it’s first HDD failure after running 7 years!) runs reliably since several weeks now - downgraded it to OS 6 because I can use the ALSA interface no longer available in 7.n - my ADI-2 DAC is connected to the 720+ using USB. My library is roughly the same, from FLAC to DSD:
R1600 in 1522+ works fine as well (although for DSD256 top PCM/DSP back to DSD256 it runs out of the default 8GB of RAM quickly; when a new memory stick arrives will test if the CPU itself is fast enough with more memory).
In PCM-only world, it has no problem supporting more than 1 endpoint, and applies conversion/convolution at ~25x speed, so I think Ryzen 1600 should be good enough.
Looking at memory usage, trying to do DSD256 → PCM/DSP → DSD256 still runs out of memory (although somewhat later) but then if you’ve converted it to PCM, moving back to DSD makes little sense anyway. Everything else, including playing highest resolution DXD tracks I have with DSP to multiple endpoints is not a problem.
I am up to ~37K tracks now, and with M2 cache in Synology performance of the UI itself is perfectly fine despiute all data (including Roon’s DB) being on spinning disks.
