Q: Put SSD to sleep?
I recently swapped out a 500 GB hard drive in my MacBook Pro running OS X 10.8.2 for a 480 GB SSD from Other World Computing. Works great and is much faster, but it does raise a question. In the Energy Saver preference pane there's an option (while on the power adapter) to "Put hard disks to sleep when possible," which I checked when I first got this MacBook Pro in late 2011. Does this option do anything once the hard drive is replaced with an SSD? If it does anything, is it likely to be helpful or useless?
MacBook Pro, OS X Mountain Lion (10.8.2)

I believe it to be useless unless you have external drives connected. Safe? Probably because that setting can also trigger external drives to sleep when not in use. It is checkmarked on my MBA because at work I plug it into a hub with external drives but I notice no difference between when it is checked and unchecked while on the road.
