I have a MacBook Pro Late 2011, 2.2 GHz Intel Core i7 with 16 GB DDR3 RAM. So not really the newest one but I want to stick with it as it works just fine (and I recently had the graphic card replaced). BUT it is quite slow when it comes to starting up or rendering videos in Premiere. (320 GB of the 500 GB are used) Since I don't know much about this, I thought I'd ask you guys in this forum. What do you think, does it make sense to replace the SATA 500GB with an SSD? Every opinion is welcome.
