As long as the memory meets the specs and is from a reliable manufacturer, it will work and there is no difference. Among the three you mentioned, I would just buy whichever you can find the cheapest.I want to upgrade my mid 2011 Mac-mini (the i5 model) from 4gb to 16gb ram. I would like to know between OWC, Corsair and Crucial brands which brand is the most compatible with this model of the mac-mini.
I've noticed the same thing. You can get the part number from crucial.com then look on Amazon and the exact same part is almost always cheaper.I always go to Crucial's website and use their Advisor Tool to find the specs of the memory for my system. Then go to the other sites and compare prices. I got Crucial RAM for $20 cheaper on Amazon for my 2012 Mac mini.
