> In text form only (no charts, plots, etc)- yes, pretty much all published 'science' (by that I mean something that appeared in a mass publication - paper, book, etc, not simply notes in people's notebooks) in the last 400 years likely fits into 20TB or so if converted completely to ASCII text and everything else is left out. Text is tiny.

20 TB uncompresssed text is roughly 6TB compressed.

I just find it crazy that for about $100 i can buy an external hard drive that would fit in my pocket that can in theory carry around the bulk of humanity's collected knowledge.

What a time to be alive. Imagine telling someone this 100 years ago. Hell, imagine telling someone this 20 years ago.
