Just a short review of a just-installed ssd in an unibody white MB... I preferred install OSX from the scratch because I had never made a clean installation since I bought the macbook in april, 2010. I also bought a usb2 case for copying the most important files and apps. I need a ssd for doing language processing over large files (around 10GB each) so I had to save most space as possible... 500GB ssd prices are still prohibitive in Brazil. The first impressions are the best possible, although I didn't stressed it too much for checking its builtin garbage collection performance. Maybe in the future I'll install another 250GB ssd in the superdrive bay. If you have any questions or comments about this specific ssd I'll gladly respond. I disabled the motion sensor for saving some battery and preventing any problem caused by this (now) unecessary feature.
