Is it possible to use Roon on NAS with only one disk. I mean SSD. I’d like to instal Roon Server on this disk and also my music files. I’ve read that ideal configuration are 4 disks: one for Roon Server, second for music files, third for RAID and fourth for backup. But is is possible to use only one disk?
It is possible and should work flawlessly with a fast SSD.
I think this was meant for 2 magnetic HDDs plus backup plus small SSD for roon´s internal database. The latter should not be running on spinning discs.
In case you have valuable/irreplaceable data it might be a good idea to nevertheless buy a second SSD of the same capacity and run everything on RAID1 if you NAS/server allows it. Just for redundancy/data protection reasons.
