This isn't just a big box with cards; it's an actual "flash drive" from Soviet times. This rarity is preserved in Akademgorodok, Novosibirsk, at the Institute of Computational Mathematics and Mathematical Geophysics. In the 1960s-1980s, there was a Computing Center here, the largest shared machine park in the USSR. Its resources were used by scientific institutes in Novosibirsk. Data was recorded on punch cards using a specific sequence of "holes." Scientists at the institutes had many such punch cards that needed to be processed on a computer. They would bring their "flash drives" in boxes to the Computing Center. Each Soviet "flash drive" weighed several kilograms. Of course, with the advent of personal computers, the need for large computing centers disappeared, and punch cards became museum exhibits.
