I'm switching over to linux on my main PC. So far i've had things set up on four main drives in windows like:

-Main OS drive and app folders(500gb SATA3)
-Dump drive for captures and downloads (2Tb SATA3)
-Editing drive for Da Vinci projects, necessary video/audio materials and editor itself (500gb M.2)
-Vidya drive (4Tb M.2)
(-Multiple external drives for backing up/exporting finished projects)

Can someone spoonfeed me to a good read or video on how filesystem in general works in linux? I heard everything installs into a /home folder, but can i have multiple drives for specific use cases like i've had for now? Can i have multiple /home folders or spread subfolders from it to separate drives?
