Neville’s posterous

There’s an interesting article in the current New York Review of books (predictably, a book review) detailing the history of the National Security Agency, that shadowy power-behind-the-power to which we surrender much of our privacy. That in itself is interesting, but I found the introduction a bit shocking: the NSA is constructing a datacenter in the Utah desert that they project will be storing yottabytes of surveillance data. And what is a yottabyte? I’m glad you asked.

There are a thousand gigabytes in a terabyte, a thousand terabytes in a petabyte, a thousand petabytes in an exabyte, a thousand exabytes in a zettabyte, and a thousand zettabytes in a yottabyte. In other words, a yottabyte is 1,000,000,000,000,000GB. Are you paranoid yet?

Heh, nice to know what a yottabyte means, never mind the Big Brother concerns :)
