Really want to get a new 2001 15" Macbook Pro, but am confused about hard drive options. Don't want to sacrafice performance for storage, so I was thinking about either the 256 or 512 SSD as my boot drive, and a OptiBay with a 750GB drive installed. Will having the OptiBay installed in addition to an SSD significantly impact the battery life of my computer, and/or will there be tons more heat generated by this configuration... I hate the fact that my 2008 MBP (with an upgraded internal 500GB 7200RPM HDD) gets less than 2 hours of battery life, and that I can fry an egg on the thing because it gets so damn hot. Anyone have any advice on how I should proceed?
