Many of the Synology packages disable disk hibernation, or more precisely DSM ignores the setting when these are installed and running. Hibernation will save power but at the expense of spin up time when the storage is needed. You may already have hibernation disabled without realising.
There's no one right way for playing media, it's whatever suits you. I would say that Plex can generate quite a bit of metadata too but it is consigned to its own locations:
If you're on a Mac with limited storage then you should monitor your usage of Plex. My Mac's Plex support and cache files are 10GB for about 4TB of music and TV/films. On my 128GB MacBook Air I wouldn't want that much used.
DSM has 6.5GB of support and cache files for pretty well the same content.
You can try Plex and create libraries that use the same media file that you're using with Infuse. See which works best.
