Gigabyte, terabyte, petabyte,...
What comes after this series: bit, byte, kilobyte, megabyte, gigabyte, terabyte, petabyte, ...?
The Economist reports in a nicely designed chart that the next three are...
• exabyte (1,000 petabytes)
• zettabyte (1,000 exabytes)
• yottabyte (1,000 zettabytes)
Yes, that last one is "yotta," as in "yotta empty your inbox sometime." (Sorry.)
This came from the Economist's special report on managing information, which is worth scanning, at least:
Information has become superabundant
How information is changing business
How internet companies profit from data on the web
...and several other items in the report are available in the right-hand column of those pages. Enjoy!
(And more thinking about the digital world is in my book Bit Literacy.)


... 1,000 petabytes ...
... 1,000 exabytes ...
... 1,000 zettabytes ...
1000 or 1024?
