A 7200RPM drive is going to use about 8W each, spun up. While spinning
them down to save that 24W is a nice idea, if that little bit of
consumption causes you thermal problems, you really have more important
issues to deal with than saving a bit of electricity. Are you even
running a fan in that case?
