Fun hard drive calculation:

	5 inch diameter platter
      x 3.14
      / 12 inches /foot
      x 3600 RPM
      x 60 min/hr
      x 8766 hr / year
   __________

    469,180 miles / year
      
A hard drive that lasts a little over 2 years continuous use puts in a 
million miles of travel.  Perhaps it would last even longer if you changed
the oil every 3000 miles ;-)
