Hi there guys, I've been so caught up in looking for the best SSD for my wife's macbook pro that I failed to realize that I may be bottlenecked by the limitations of the SATII on her laptop. I'm here asking myself why would I focus so much on read/write speeds that I may not be able to get through an SATII. I was considering the M550 or the OWC Mercury Electra 3G but now considering the limitations of the laptop, I may opt for a M500 or an MX100. Anyone think I should still get the OWC or can you suggest a great SSD for my current "antiquated" set up? Thanks.
