What makes SharePoint unique
SharePoint wasn't originally designed as a storage platform, and was instead intended to be a company's local intranet for communication and collaboration.
While SharePoint has expanded to become the primary cloud storage method of Microsoft 365 organizations, it has also retained its intranet functionality. Because of this, SharePoint is structured differently from other cloud storage platforms.
Instead of traditional drives/folders, storage is broken down into Sites and Document Libraries within a site. A Site is a container for organizing information, including files and other resources. Document Libraries are storage centers for files within a SharePoint Site. One Document Library is included by default in every Site, but one Site can have multiple Document Libraries for organizing information.
SharePoint sites can function both as a website and as file storage by accessing files in the site's backend.
How storage is allocated and handled
The amount of storage available in SharePoint depends on the base storage plus the number of licenses the organization has. Each user adds 1TB to the pooled storage in the organization (on most plans), which can be used across SharePoint and is separate from each user's personal OneDrive.
Each site collection can hold a maximum of 25TB of data, but admins can reduce this threshold for specific sites. Items in recycle bins count towards storage as well as saved versions.
Additional storage can be purchased in 1GB increments as a file storage add-on.
How user management works
A user is an individual in a Microsoft 365 organization with a unique email address. Each licensed user receives a personal OneDrive and email account.
Unlicensed users with restricted features can be added to the organization at no cost.
Users must be added to SharePoint separately after being created. Both licensed and unlicensed users can be added to a SharePoint site, but internal users are required to be licensed according to Microsoft's terms of service.
How content ownership works
SharePoint sites and content within are owned by the organization by default, and can be further restricted through SharePoint Advanced Management.
For OneDrive, each user is the primary admin of their own OneDrive account and files within, and SharePoint admins do not have access by default.
While individuals own their OneDrive content, Microsoft 365 Global Administrators can take ownership of a user's OneDrive in the Admin Center.
How sharing and permissions work
Files and folders within a user's OneDrive are private to them by default. Users can opt to share these items out with individual users or groups. Admins can control which content can be shared and who it can be shared with.
In SharePoint, the following permissions can be applied at the Site level or on individual files or folders:
Viewers have read-only access.
Members can add and edit content, but can't change Site settings.
Owners have full control to directly make changes, including deletions.
Files and folders within Sites and Document Libraries can also be shared with additional users or Groups, including external parties.
All Sites/folders/files can have a link generated that can be shared both internally or externally, with optional expiration down to a specific day.
How syncing with local storage works
SharePoint content can be synced to local storage using the Files on Demand feature. Syncing can be done with OneDrive shortcuts or by direct syncing with local storage. When synced with local storage, SharePoint files appear as the name of the organization, and each library is a separate subfolder.
How billing works
Microsoft 365 bills on a per-user basis with several tier levels that add more features across the organization. All business tiers have access to SharePoint, while higher tiers add CoPilot and other incentives.
Additional storage can be added in 1GB increments.
