So I installed my 500gb in the Optibay of my early 2011 13" MBP. I've noticed it spins up and down and I've read a few questions in regards to that where it talks about sleep timers and unmounting the drive. My question is, If I unmount the drive, isn't it technically unavailable then until it's mounted again? Since that drive contains all media files, pictures etc.. If I wanted to play a movie the device would require to be mounted at all times. Am I wrong here? Would the changing the sleep timer affect the drive in performance in anyway? And last night, was I supposed to install the SSD in the Optibay instead of the HDD?
