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.

Where did you get that from?
I think that was just an example. Tiered storage is fairly common, though. NVMe SSDs are faster than SATA SSDs, which are way faster than hard drives. Amazon has a “glacier” tier of cloud storage which is pretty cheap, but it can take time (hours) or money to download your data. Great for backups though.
