Well the human brain is pretty amazing....the ability to prioritize and process input and output without conscious thought.....making intuitive connections. We do have our limits, though...we just encounter them much differently than a machine.
In my logic, human has limited capacity. And there were many moments in my life, when I understood that my memory is too full. Well, but yes, I am not a computer based on algorithms, I can feel, create new oportunities which weren't showed for me.
One alternative point might be that hard drives don't build their database erratically, subjectively and use faulty irrational shortcuts! While our brains are pretty awesome, they are not like a computer. That's good though, because it makes life more interesting. Using a perfect machine would get boring. Constraints make things interesting.
OH! and pouring coffee on your hard drive won't make it go faster.
