I would say they would need to toss all the 11 scores and do it again without the drive being encrypted (as they acknowledged in the article). Then run modern apps to compare, because ram usage doesn't say much about speed. Newer games in specific do benchmark better on the same hardware from 10 to 11, showing that while the ram usage is b Higher, it is better used for the time period it is being produced for.
Write speeds and such are up as well apparently.
