So, long story short, Got a mid 2012 a1278 MacBook Pro from one of my best friends, but it only had 4gbs of ram and was an i5, 1600MHz dual core. So first, I got one 8gb RAM stick so at least I'd go from 4gb to 10. EXPONENTIAL difference. Then, when I started reading about the longevity of HDD drives, and considering how old this Macbook is, I figured, if I want this to last as long as possible, I should get good parts or it. So to be delivered Monday WAS another 8gb Crucial 1600MHz DDR3 RAM stick and the Crucial MX500, 500gb internal SSD drive. for some reason in my mind I thought that have the same manufacturer for the ram and SSD would make them perform with better sychronicity, but from literally every review I've read, the Samsung 860 Evo wins out on total speed. So I cancelled the Crucial MX500 and got the 860 Evo. I'm sure the question has been asked on here like a million times but, which one do you guys think is better? and is there any actual connection between the RAM and SSD? (Like, that would be to say their system integration would theoretically have the easiest compatibility. My Best friend/tech guru/guy I got the computer from suggested the Samsung and said it's the best. Personal experience guys? Care to weigh in? Amazon has a good return policy so if anything I could always exchange it if I became convinced the other MX500 was that much better.
