Energy Saver

SSD and Energy Saver in Mac OS X

energy_saver

Now that I’ve installed a solid state drive (SSD) in my MacBook Pro I’m wondering if the checkbox about spinning down a hard disk to save energy has any meaning anymore.

Maybe a more interesting question is, does that checkbox even exist on a MacBook Air? How context sensitive is the Energy Saver System Preference pane?

This may sound like splitting hairs but given that an SSD mimics a hard disk (is installed instead of a hard disk in the same slot) while the solid state memory on a MacBook Air is soldered to the main system board, energy saver might treat an SSD differently from the MacBook Air’s solid state memory.

Anyone out there with an Air care to comment on this? Does that highlighted checkbox even exist on a MacBook Air?
