Hi @Mervyn_Lim ----- Thank you for the follow up and verifying that information for me.
If you intend to keep using the DS1815+ as your Roon core I would strongly recommend considering either installing an SSD in the unit OR using an SSD via an external enclosure for your Roon DB. Leaving your files on a spinning disk should have no consequences but I would not be surprised if you encounter performance issues with your core as your library grows.
Taken from the Roon knowledge base:
"Which NAS devices are supported
Most QNAP and Synology devices with a 64-bit Intel CPU and at least 2GB RAM are supported.
We strongly recommend 4GB of RAM and an SSD for the Roon databases. Your music files can be on spinning disks, but ideally the Roon database should be on an SSD. This one optimization can provide the single biggest improvement to Roon’s performance and user experience.
Sound Quality - Rule #4: “Don’t under spec the server”
"Slow servers, NAS’s, and network connections can affect sound quality by preventing the Output components from receiving audio in time. This can manifests as clicks, pops, dropouts, and static.
Both Roon and all RAAT outputs use strategically placed memory playback buffers to limit the impact of this sort of thing, but poor performance can still lead to behavior in the CPU or networking hardware as it handles the audio stream in fits and spurts.
Invest in your server components just like you would in your other gear, and remember that there is no downside to a Core i7 with a fan if you’ve got it located two rooms away from the listening area. Take a look at our hardware specs, and try not to come in below our recommended level, and especially, plan on using an SSD to store Roon’s databases.
