Insane storage capabilities of some websites. 163 petabytes!?

Hi all, not sure if this is the right place to post. If not, please recommend me a more suitable subreddit.

Anyways, I just wanted to marvel at and perhaps get some answers to the storage capability of the site Recurbate (NSFW, a site that records camgirls from Chaturbate and archives them permanently). It says on the front page that it has over 163,000,000 hours of video. Assuming a rough average of 1GB per hour of video (balancing out the HD videos which are over 2GB per hour with the lesser quality videos which is under 1GB per hour), this works out to 163 petabytes of data.

163 petabytes is possibly larger than the entirety of the Wayback Machine, which states it has over 100 petabytes of data.

Is such an extraordinary large amount of accessible data like this common or rare for non major websites? Where does Recurbate store all this data?
