"Application results were much more impressive. Because the drive learns, the first time you bring up an app it happens at disk speed. But the 2nd time!"

"Boot performance sucked compared to the old drive’s ~45 second boot"

Boot performance was improved by doing a clean install, however, the best the reviewer got was close to the old HDD speeds (45 seconds) not a Macbook Air's boot times with SDD (15-20 seconds).

If you watch the videos, the speedups being boasted on the review involve opening the application, closing it, and opening it again, without running anything else.
