We’re gonna need yots of storage

I’m mentally still measuring computer storage capacity in gigabytes. A gigabyte is 1,000 megabytes, or 10 to the ninth power bytes. One thousand gigabytes is a terabyte, or 10 to the 12th power bytes. I hadn’t even gotten around yet to wondering what comes after terabytes. But thanks to the Federation of American Scientists, I now know that 10 to the 24th power bytes is a yottabyte.

And how many bytes is that? Yots:

If one byte of data were used to image one square meter of the Earth’s surface [and if it were, then the picture resolution would be lousy, but let’s work with them here — Lex], then 1.6 Yottabytes would be generated by imaging the entire surface of the Earth every second for a hundred years, the [defense advisory committee] report explained.

This will be very easy for me to remember because of something that happened around the time of Victoria’s third birthday. I asked her what she wanted as a birthday present and she said, “Bayoons, Daddy! Yots and yots of bayoons!”
