data is physically stored in "cylinders" on a disk .... each time the disk
head has to move, it takes lots of time .. tens of miliseconds

with less head movement, your system will appear to be lot faster
        - use a 1GB compact flash and see how much faster it runs
        compared to a regular hd ... doing lots of disk i/o

        while < true > {
          time "ls -laR / | md5 "

          # now flush the disk cache clean, and move the head to track0
              so it doesnt read "disk" from memory
          #
        } # fun stuff
