The German magazine c't has a regular column about new hard disks and their
access speeds. The did note that some disks actually can switch from track
to track faster than from surface to surface, probably because they need to
re-sync to the servo information on each new surface. Since the
manufacturers aren't stupid, they know this too, and thus reordered the
sectors so that the disk first walks down one surface, then up the next, ...
I think that any fancy reordering should already be embedded in the disk
itself, therefore it doesn't make much sense to put the same into the
kernel.
