    Looking at diskprices.com, lowest prices for storage are around $8 (used) or $15 (new). I didnā€™t look too hard, but a 30TB SSD for $80 (~$2.5/TB) seems wrong?

    100K TB * $15/TB = $1.5 million

    Assuming 100PB is the amount of data, weā€™d also need redundancy. Idk what best practices would be, but Iā€™ll say 3ish copies, so 300PB total.

    So a grand total of ~$5 million.

    Which is crazy cheap, all things considered. Like, it would be no problem for a single rich person to handle that.

    Hell, subsidize/give away cheap little computers that you just plug power and an Ethernet cable into. Raspberry pi + 4TB drive ($60) + casing would be likeā€¦ $100? Though I guess youā€™d need 75K of them, and the cost per TB is pretty bad.

    This guy is 20TB for $280: https://a.co/d/17UOtFi

    If we stick with $40 of overhead for rpi etc, thatā€™s $320 for 20TB ($16/TB), and weā€™d need 300PB/(20TB/unit) = 15K units. And at $320 each, all in would be $4.8 million.

    The software seems to exist for connecting them allā€¦ So idk seems like it would be absolutely feasible? Would be interested to learn if Iā€™m missing a major cost.
