Noise levels on a 2 bay and 4 bay is actually the same -https://www.synology.com/en-uk/products/compare/DS220+/DS420+/DS920+Smaller NAS often have a louder fan, because a bigger fan needs to spin slower to achieve the same cooling levels.You are right with the HDD choice. WD Red will be quite. Or you could make a setup with 1 or 2 SSD for system file and OS storage and HDDs for multimedia. But having only HDDs is just fine.Alternatively, you could have another NAS located somewhere else. You can link this extra storage space to your existing NAS inside the Plex. So one NAS is a Plex server with some multimedia and another NAS serve as additional storage space.I hope this helps.
