Each scanned ballot is likely the same size, and making more of them is just a matter of duplicating files... easy to do. 50K votes per USB drive strikes me as very peculiar - maybe a limit of the USB drive they're using, or some sort of limit on the Dominion scanners.
It's also very unlikely that actual USB drives would be exactly 50K each.
Sounds like something that would be in the Dominion voting user manual.
Hmmm....there could be a limit if each “vote” was a unique ballot image. Doubt it would happen to work out to exactly 50k but maybe close. Does anybody know the file type of the scanned ballots and the expected size of those scans?
