Thinking of switching from QNAP to Synology or Asustor

Perfect, that’s what I was wondering! Thanks!

Last question I had is if I go the TrueNAS route, then could I use just any NAS? I mean, is it like Windows? I could just use my QNAP NAS to install TrueNAS OS and just delete the QNAP OS?

Great! I see Plex on there so I guess that should be easy to setup as well. Only thing remaining would be a music that manages ID3 ratings tag. Probably that a subsonic fork works.
