I have been reading all the discussions I could find pertinent, over the last couple weeks... Many different points of view, different ways to go... I am very close to buying a new MacBook Pro... First question, which third party SSD to buy, likely 256 GB maybe 512... Specifically for the 2012 15" MB Pro, NOT Retina... The particular and actual ones, so to speak, Crucial, Corsair, or other makers... I ask this partly because I've looked on the Crucial site and what they recommend for the new 15", and their # on it doesn't seem to match Crucial's manufacturer numbers on sites like OWC, J&R, etc... Got me confused... Any help on this greatly appreciated... Criteria for me in order of importance are quality (durability) and reliability, costs, speed... With quality and reliability including its interface with the new MB Pro... Additional thoughts more than welcome... Second question, which ram upgrade re manufacturer again... Same criteria as above... I understand that 1.35 volts is important... Some seller's sites ram specs don't show the voltage, MacConnection for instance... And again, which particular ones if possible... Many thanks, John.
