It may still be true with moving-head disks, but all that geometrical
information is hidden from the OS these days, behind linear sector
addressing done within the drive itself.

I think the basic thinking nowadays is that, if you?ve having to do
disk I/O, you?ve already lost several orders of magnitude in transfer
speed, and no amount of trying to optimize head movement is going to
make much of a difference to that.

In other words, if you have to swap, your system is in trouble,
anyway.
