To stretch the analogy a bit: it’s like virtual memory. Not as fast as RAM, but there’s an effectively infinite amount of it.

  Probably a good analogy. And it's also incredibly slow so you need to have a good amount of RAM and CPU cache.

  Since one's brain is not able to translate a thought into a search engine query which leads straight to the answer, that virtual memory analogy doesn't work at all.
