I'm hunting around for a SATA III SSD for my 2011 17" MBP. The Crucial C300 256GB SSD sadly did not work, couldn't even get it to format. So I'm sending it back to Amazon. Are there any SSDs on the market that should work without issue? I'm guessing SATA II SSDs work without problems? Should I try OWC? I'm also thinking of just sticking with the 750GB HDD for a while until the 500GB SSDs come down to the sub $500 price range... Thanks for any help.
