I was going to post this to the SSD buying guide but as a reply I can't poll you guys. So here it is: MBP 15 (Mid 2010) v6.2. Looking for a 512GB SSD to replace or go along the current 500gb drive. I am loosing the DVD drive because I don't use it. Should the SSD replace or be in addition to the current drive? does it make a difference where each drive is installed if I retain both? The drive choices all exceed my speed needs and I know they will be limited by the controller I have. But I am buying up...I will be moving this drive somewhere else...probably another MBP. Criteria is: 1: trouble free 2: performance 3: conserve power as much as possible for a longer battery life.
