Parse File image , actual location on server?

using Parse Server FS Adapter , If I store all files on my server rather than in DB, will it help at some level ?
thinking of not using any third-party paid services for file storage and using our own VPS. to save some bucks.

I don’t much about Parse Server FS Adapter, but what I understand is it helps us to create files on our server, not in DB correct me If I’m wrong.
again pardon me for asking a silly question.
