I'm thinking about buying a macbook pro (latest 2012 version) and it seems sensible (from a financial point of view) to buy the standard built in hard disk and do the upgrade to SSD myself.
In order to get the most bang for my buck, I'd like to know what the maximum read/write speed of the SATA interface in a macbook pro supports? i.e. is it worth getting a 600Mbps or 300Mbps drive? Is it SATA 2 or 3?
