    So scan density was basically physical fragmentation? Is this correct?

    No.

    SQL's not aware of physical fragmentation, of how the files are placed on the drives. Which is why I said not to mix up logical/extent fragmentation (position of things in the data file) and physical fragmentation (position of files on drives)

    Scan density was just confusing.
