Detailed Description

Storage on the database itself.

This is likely to be the slowest backend. However, it scales okay and provides random access. It also doesn't need any special setup, the database table is added with update.php together with other tables, which is the reason this is the default backend. It also works well on multi-server setup without needing for shared file storage.
