Hey, I have a MacBook Pro 2.66 from mid 09 and I'm thinking about updating the hard-drive myself to one of these SSD drives. I have a few questions however, and I'm hoping someone can enlighten me. Firstly, how would I go about installing the hard drive. I know I'll need to un-screw the laptop case and I have the PDF from apple with the instructions on how to do so but; 1. Would I need to install Mac OSX into the SSD BEFORE installing the hard drive or do I swap the hard-drive and THEN install OSX? If it's the latter, what happens to the data on the original hard-drive? Will it automatically sync over if I connect it with a USB cable to the Mac when the new SSD hard drive is installed? 2. Should I wait a few months before doing purchasing a SSD card or are they worth it now? I'm hearing a lot of contrasting opinions, people talking about Snow Leopord not being compatitable with TRIM and therefore the SSD drive will get slower in as little as 6 months? Then on another forum apparently it will last as long as 50 years?
