hi, im planning to buy my very first mbp (2011) and i have a question about upgrading to a 3rd party ssd because what apple has it priced for is ridiculously expensive!! Q1: if i buy a mbp stocked with the 500gb s-ata drive, can it easily be replaced, say, with the ocz vertex 2 ssd, considering its dimensions and what not? I don't know how it looks inside but am i also able to do it myself with ease? ( i have experience with building my own windows-based-pc; so hardware is familiar to me ) Q2: i will be using my mbp for architecture school and i'm assuming i'll use up a lot of space on the vertex 2 240gb ssd for music, pictures, 3d projects, videos,etc. is it wise to go with this and just carry around an external drive for these personal files? or should i stick with the 500gb 7200rpm HDD? (i'd liek to get an opinion from a student in my position or any other opinions would be nice) thanks for your time !
