I have a 17" MBP with the 500GB 7200RPM HDD, would like to upgrade to a 256GB SSD for all the performance gains, but mostly because I hear the HDD click whenever I move the machine quickly. Guessing it is parking to ensure no loss of data, but since SSD can take far more shock than a HDD, looking to go that direction. What do you recommend? Any gotchas? This is my first Mac since the late 90s, can I do a fresh install from the SL upgrade disc or do I need to start with the discs from initial purchase then SL upgrade? How do I go about restoring my data from my time capsule via time machine?
