If you ask me, I still believe that google fetches and stores a copy of pages for which you add noindex meta tag. noindex just prevents them from listing them in the results in any form.

But when you disallow the googlebot through robots.txt, they might not (though not sure) store a copy of the content on such pages on their servers, though they do list them as urls, as if they are stub pages.

I also believe that they have copies of pages with "noarchive" meta tag on their servers though they don't show a cached link for them.
