I think I have decided to go with the Samsung 500GB EVO to upgrade my 2012 15" MBP instead of the 256GB Pro. Can't really justify another $100+ for the 512GB Pro and the more I think about it why not get the EVO to have the same drive space I have now for a better Dollar to GB. I know it is slightly slower than the Pro with some benchmarks, but doubt I would actually notice it myself. And what I read the increase is only around 5% and the EVO is a slightly faster with random reads. Also, both will outlive any laptop I own so not worried about the Pro lasting longer. One thing I noticed with the EVOs I have looked at. Rip off Best Buy has it for $100 more than Amazon, but the model number is different than what Amazon has as well as Newegg. Is this just a case of a "special" model for Best Buy so they don't have to price match? Best Buy has a MZ-7TE500LW Amazon and Newegg list a MZ-7TE500BW So before I pull the trigger is there any reason NOT to get the EVO? I think I am pretty set on the Samsung, as it seems to have the most consistent reviews and is up in the top of most sites.
