I have a bit of trouble reconciling @aisg's posts. In their first message, they have 2 libraries, one that sounds like the equivalent to my Intake with 218,321 books and the other with 1,253,450,253 books. The library with 1.25 billion books is stored on a 10TB external WD drive. A bit of quick math gives an average of 7,977 bytes per library entry (ebook, cover image and opf file) which strikes me as being a rather unrealistic size.
Your forgot metadata.db. Just my metadata.db file alone is 5587 bytes per book (highly variable of course, but I divided it's size by the number of books I have in Calibre as a rough estimate). So we're down to 7977 - 5587 = 2390 bytes per book. I doubt that's enough to even hold the one-page publication details and copyright statement of a book, much less the contents.

I'm sure they must have meant they have a 10 petabyte external drive and not just a mere 10Tb one.

[edit]p.s. - The Calibre library under discussion holds 5x the number of books in the Library of Congress, the largest library in the world. That is one mess of eBooks. I wonder where they all came from?[/edit]
