It says they stored 44 petabytes total (70 billion * 700 kilobytes), and 700 terabytes in a single gram (which is 5.5 petabits, not 4.4 petabytes).

  in the paper, we say 1.5mg per petabyte at large scales. we only encode 650kB or so. this seems a little sensationalistic. we are far away from being able to do 1 petabyte of arbitrary information.

    Wait, 1.5mg per petabyte at large scales? Wouldn't that mean a gram could hold (1000/1.5) 667 petabytes and presumably scalable to many grams (eventually)? I understand it's only 650kB right now, but the density is obviously still incredible.
    • skosuri 14y ago
      yes. density is astounding. that's why it's in science i presume. mostly because people forget how dense dna information really is.

        > i presume you are either the most humble senior author ever or jerking all our chains. possibly both. congratulations either way.

          this is my first senior author paper; i imagine i'll be more haughty after I start teaching a few classes.
