Have a MacBook Late 2008 Unibody aluminum and have the SSD eigebaut there. I can only say that the MacBook is back on the amount of time! App's be reopened very quickly and there are no delays! I can here, although not specify benchmarks and the feeling is subjective, but the computer running times Felt 3 to 4 times faster than before! SSD screwed in, booted with Maveriks via stick and then pulled up the backup via Time Mashine and the box is running. Therefore 5 stars!
