ELI5: Why can Google search the entire Internet faster than a computer can search its hard drive?

An average computer has around 100gb to 1tb of data, yet Google, which is searching millions of websites, which is thousands of terabytes of data, can search much faster. Why is this?

Google doesn't search the internet when you run a google search, they search their highly optimized indexes from their own database. The database is formed by google "spiders" that crawl "the web".

If you wanted, you could build a highly optimize database of your hard drive's contents that you could run searches against. But that would take up a lot of your computer's storage space, processor time, and isn't the best use of those resources.
