There is a chart/graphic someone did, a woman I think, about all the
storage required to store the world's text, and audio, and video and
the public web and the dark web, and so on, broken out.

I need a link to that picture somewhere online.

One of the best sources of data is the "How Much Information?  2003"
study that has a series of graphs on stored information (rather than a
single representation).  It's about 100 pages in a PDF file, but is
this helpful or is it what you're looking for?

University of California at Berkeley
School of Information Management and Systems
"How Much Information?  2003"

Best regards,

You might be thinking of this image:

which boils down the Berkeley study to a single pie-chart (about half
way down the page).

That was not what I was looking for, but the report was good, so I am
willing to take that as an answer.

There are actually 2 Berkeley reports, the 2003 version being the latest:

UCal Berkeley
"How Much Information?" (2000)

UCal Berkeley
"How Much Information?" (2003)

Note too that Bright Planet has done an interesting study of the "deep
web," concluding that it is 400 to 550 times larger than the public
web.  This is a link to the HTML version, but if you open the PDF
version (the link is at the top of the page) you'll find much more
interesting graphical representations of the study:

Bright Planet
?Deep Web White Paper,? (Berman, July 2001)

Google search strategy:
"deep web"
"dark web"
Berkeley + SIMS + "how much information"
