Wonder if 45 terabytes of hentai is more or less than a lifetime supply.
Depends on consumption rate, of course? And media format sizes. It's really hard to estimate, though, as size of individual works can vary wildly (most are probably in the 20-30 image range, but there's lots that are fewer and many that average somewhere in the 200 images range, plus CGI collections and whatnot that can go even further).
Super super rough guess, if you baseline with the 20-30 ones they probably average somewhere in the 20 meg range for okay-ish quality. Say 25 megs per set for a working number, considering the entire 45 tb collection to be made of them -- 1.8 million works, under those assumptions.
Let's say they're using it for pleasure instead of something else (art reference, translation work, cultural studies, whatever), start when they're 12 and stop when they hit 65 -- ~19,345 days. Libido's pretty active and there's no relationship interference, so they average out to two sessions a day. Folks seem to go through more than one at a time, so let's just asspull three works per session, for six per day for 19,345 days. Perspective porncritter is impeccably omnivorous with an infinite strike zone and no fetish they can't get off to, and refuses to use the same one twice (well, same collection of files -- reuploads or translations are fair game).
Comes out to 116,070 works consumed over their lifetime, less than a tenth of the total proposed collection. None of those numbers would be terribly accurate, and any prospective user is probably a
lot more discerning than our omnithirsty horndog, but the rough answer to "is it a lifetime supply of porn" is "yeah, probably a couple times over". Share with a friend, I guess.
