Yep, this is how I do it on my NAS, which is some RockPro64 board attached to WD Red spin drives. I have music, movies, game saves, documents, pics, etc. that equal around 1.5TB and I don’t seem to get excess scanning when “watch files” is turned on.
I’ve had a similar problem across various distros and several years: everything is fine for a while, then suddenly several games have audio crackling issues. I can usually (but not always) solve this with a
PULSE_LATENCY_MSEC=60 %command%
in the launch options; sometimes a different number, such as 20 or 30, works better.
