Surely that does not make sense, having all my appdata, domains, and vms on an nvme drive is the fastest way to do it and the slowness of parity only affects writes. So having it parity protected does not make a difference when running a VM or docker as it is mostly reads with some small writes. My vm’s write large data sets such as games to an unassigned drive and my plex metadata is on a separate SSD (parity protected), but again that is mostly reads with some writes.
I also use CA Backup plugin.
My issue with the yellow indicator was annoyance rather than worry as I couldn’t work out what file was on there.
