A root folder makes it super simple to deploy new shares to users. By enabling users to view all resources from a single starting point, organizations can eliminate the confusion associated from deploying many individual share points to employees.
Google Drive supports a search-first, browse-later mentality. Best practices for dealing with traditional file servers call for deeper folder structures that rely on categorization to make browsing easier. When it comes to searching, however, flatter structures are the way to go.
Role-based permissions make auditing and change management a snap. If a new employee is hired, IT can quickly assign resources simply by placing the new user account into the proper role groups that correspond to their job function.
