We added the disk database specifically for facilities that don't need, or want, the complexity of PostGres. PostGres needs a server app to run and is ideal for facilities with multiple systems that need to share projects all the time.
Disk database saves the project metadata in a simple folder structure that easy to backup with normal IT procedures, even TimeMachine or a disk copy.
The disk database files are located in logical paths, details in the manual and you can still export whole projects to import to a other system if you wish to share.
I recommend using disk database unless u have a specific need for live sharing of projects
