Like others have said, their storage needs are staggering. I would not be surprised to find that YT's storage is bigger than the entirety of Google's web archive, which is mostly text. Possibly much bigger. If YT were not part of Google, they would still need Google-scale infra in order to handle the insane number of pixels they're streaming every second of every day.
