Keeping all projects and events on the scratch disk is usually the best way to run things. When you render the files go into the project's folder. So these are media files which work best when played back from a drive other than your startup disk.
That said, if you duplicate an Event, it will copy everything to another drive. You'll find the command in the File menu.
