Quettabyte[edit]
I learned that very soon SI will officially have the prefixes ronna and quetta. How big would a quettabyte be?? Is the amount of storage on all computers that have ever existed anywhere near a quettabyte?? Georgia guy (talk) 01:32, 31 October 2022 (UTC)
- No, nowhere near a quettabyte, which is 1030 bytes. According to this, there was about 44 zettabytes in all computers in the world in 2020 and the number is expected to grow to 175 zettabytes by 2025. Even the latter number is more than 5 million times smaller than a quettabyte. (Historical computers which no longer exist won't change this number much -- according to this, there was only 2 zettabytes of data in the world in 2010.)
