Incredible: just with the new solid state drives built into MacBooks Air, Apple achieved an increase of up to 217% (!) In performance. And look that the model tested the TS128E, from Toshiba; some units also leave the factory with Samsung's 830 line SSDs, which promise to be even faster. (OS X Daily)
