It depends on your usage. If you spin down and spin back up every 10  
minutes, you will kill your drives faster. If you spin down and spin  
back up in a few hours, you'll get more life out of the drive. My  
drives run about 10C cooler now that I spin down after 31 minutes of  
inactivity instead of constant spinning all the time. (3 media drives  
all sit snugly together in my Zalman HD-160 case and my OS/MySQL drive  
sits separately, always spinning.) The same can be said for anything  
that's made to burn out over time - lightbulbs, cars, etc. Leave them  
on or constantly shut them down when not in use? Back to my original  
comment.. depends on how much you are using them.
