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?

OWC has tested it and confirms that..
which is the SATA Revision 3.0 speed.
They've also setup a striped RAID which benchmarked at "over 1000MB/s read speeds and write speeds that nearly hit 900MB/s".
Regarding the Macbook Pro 13" (2012), OWC recommends using a 6Gb/s SSD only in the main bay, as the 6Gb/s performance of the optical bay is very poor. 3Gb/s models however work without problems in the optical bay.
