Why Put Your Mac to Sleep?
In Mac OS X you’ve a number of options for putting the Mac and its hard drive(s) to sleep when you’re not using them. When a Mac and its hard drive are asleep, they’re still on but at that time they consume a lesser amount of power. It is also much quicker to wake a Mac or hard drive(s) from sleep mode than to restart a Mac when it is completely shut down, hence it is often preferred by people to put a Mac or hard drive to sleep instead of shutting down when not using it.
