A friend of mine is going to put an ssd disk in his Macbook Pro 17 late 2011. I have been recomended the Samsung 840 Pro 128 gb, for mac use. I also see they sell Samsungs 840 evo 120 gb , a litle bit cheaper ? Whats the difference between theese two? The evo uses a nother type of storage memory thats not suppose to last so long that the pro? Is the evo also mac friendly, as the 840 pro is suppose to be ? Or am i wrong her?
