Already mentioned and it's a minor point, but regarding putting files into the database... When I worked at MS on SharePoint, we actually transitioned from storing files on the file system (Windows) in V1 to storing files in the database (SQL) in V2 for performance reasons. For a system that works with lots of files, the file system isn't the place. If it's static content, send 'em to a CDN. If it's active content, put 'em in a database for the reasons Dave mentioned (concurrency, write speed).
