I know memory is fairly cheap but e.g. there are millions of new videos on youtube everyday, each probably few hundred MBs to few GBs. It all has to take enormous amount of space. Not to mention backups.

That’s the difference between getting a video served off a disk off in some random DC in some random state vs. the videos being served off a cache that lives at your ISP.
It’s not offline storage vs. disk, it’s a special edge-of-network cache vs. a video that doesn’t live in that cache, but is still on a hard drive.
