That is an old assumption from the infancy of software raid, less than optimal 
  installed ram, and slower processors. When ram was expensive, you used more 
swap because it was cheaper. But ram is so much cheaper now that it make no 
sense to run a machine that needs to touch swap except in an emergency.
