5D glass storage 'memory crystals' promise up to 13.8 billion years of data storage resilience, which is roughly the age of the universe — crams 360 terabytes into 5-inch glass disc with femtosecond laser

          Streaming quality will allow for more, production for bluray would be less.

          Figure around 8GB per hour streaming, UHD at 60fps and with HDR it’ll be more like 45-60GB/hr, let’s call it 50GB/hr for estimation.

          With streaming quality, it’ll be roughly 45000 hours, and at a much higher bluray UHD HDR encode quality, its about 7200 hours. Roughly.

          If I did my math right and assuming 35Mb/s bitrate (4.5MB/s) you can probably fit around 2.5 years worth of your po…pular media of your choice

    So this would be really neat for an Apollo (H:ZD) style repository of knowledge in case of global civilizational collapse. I’d love to give the people three hundred years down the road a hand and help them build solar panels and make penicillin. I’d love to share our stories with them, or at least leave them a copy of Bill Wurtz’s History of the Entire World, I Guess. This seems like a great use case for that, only the question I keep coming back to is “how do we tell them how to read it?”

    “First, make a computer”? After global civilizational collapse?

    And before anyone says books, let me point you to the Library of Alexandria, Nalanda University (it’s said the university smoldered for a month after the mongols torched it), and the Bronze Age Collapse. Fire and Water have a way of making books disappear, this at least seems far more durable and much more information dense.
