Drive Admin: Only refers to the administrative permissions inside of the Drive UI. Such as inviting users, changing drive roles and creating groups. Besides this the Drive Admin can behave as a normal user.
Drive User: Normal user. Has a home folder that they own. Every file they upload can count to their storage quota.
Drive Guest: Slightly higher privilege than the normal Guest user. Drive Guest referes to a known collaborator. They get a normal user account, but not a home folder.
