Nice article, great calculation. There's a much simpler argument for 128 bit storage though: the observable universe has at minimum 10^79 atoms in it. Even if you could use each and every one of those atoms as a bit to store data, you'd still have more than 50 ORDERS OF MAGNITUDE left in ZFS for the rest of the data. We're probably safe.
- cperciva 16y agoYou realize that 2^128 is much less than 10^79, right?
- barrkel 16y agoA handy rule: log of 2 to base 10 is a bit more than 0.3, so divide the power of 2 by 3 (i.e. approximately multiply by 0.3), and you'll get an approximation of the power of 10. By this, 2^128 is in the region of 10^40, a lot less than 10^79. (It's actually about 10^38.5.)

- ten7 16y agoAhh shit, totally lame brained that.
- ten7 16y agoYea, I screwed up. What the hell was I thinking? Thanks for down voting: it's deserved.
