I have a new MacBook Pro that came with a 750GB HDD that I kept in its original location. I also have an OWC 120GB SSD (360 FW)that I purchased back in March that was used in another system. I've put the OWC SSD in an OWC Data Doubler and have it installed fine. Already got Lion up and running. I know there are optimization tweaks that you can do for the SSD, such as setting hibernate to 0, deleting the sleep image, disable putting the hard disks to sleep, turning off the sudden motion sensor, etc. How am I supposed to correctly implement these on this dual drive setup while still wanting the HDD to spin down to save power and for it to use the SMS in case it's needed? For example, if I disable powering down hard disks, that also is going to affect the HDD right? So, it will be constantly spinning? Is there a way to tweak for the SSD while maintaining power saving features of the HDD?
