Whatever terabytes or petabytes of data we have in indices today, is it all served from memory? I remember Google saying at some point they went fully in memory searches, don't know if they have kept at it or if it's the standard.

The caching of images and web pages might be more difficult. Plus, Google could easily just cache the the results for the top million queries without much ram at all by comparison.
