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.
