Punch cards? Stored correctly there's no reason they couldn't last many human lifetimes. But... Yeah it'll take a while to encode everything.
I would have thought that with modern technology we could come up with something like punch cards but more space/time efficient. Physical storage of data - only one write cycle of course, but extremely durable. Even just the same system as punch cards but using tiny, tiny holes very close together on a roll of paper. Could be punched or read by a machine at high speed (compared to a regular punch card, presumably still Ber slow compared to flash media).
Paper doesn't last centuries. Anyway, punched cards don't have a storage density that's adequate for modern data volumes. You need something that'll durably store nanometre-sized marks.
Yes that's what I'm thinking, some modernised physical data storage technique.
