So I have a 500GB HDD in my MBP (and it's probably more than I'll ever need) But I always like to have as much Hard Drive space that I possibly can and ever need, to be on the extra-prepared side. I want to upgrade to a 1TB or a 750GB Hard Drive. I know nothing about Hard Drives other than 5400 RPM is slowest and 10000 RPM is fastest (For SATA Drives). So I have a few questions to ask you all. What are the price differences going to be compared to 5400 RPM vs. 7200 RPM vs. 10000 RPM? What manufacturer makes the best, most compatible Hard Drives for Mac? How easy would it be to keep my current system in tact? Would a simple CCC and Time Machine backup work, or would I need to reinstall and copy everything manually? How do I format the Drive? When I put it in will the computer automatically format it, or do I need to buy a utility that will let me plug it in as an external to format first?
