Data and Goliath: The Hidden Battles to Collect Your Data and Control Your World

Description

According to the New Hacker's Dictionary, Schneier coined the metasyntactical expression "Alice and Bob".

ref:0.133-5:

Storing the voice conversation from every phone call made in the US requires less than 300 petabytes, or $30 million, per year. A continuous video lifelogger would require 700 gigabytes per year per person. Multiply that by the US population and you get 2 exabytes per year, at a current cost of $200 million. That’s expensive but plausible, and the price will only go down. In 2013, the NSA completed its massive Utah Data Center in Bluffdale. It’s currently the third largest in the world, and the first of several that the NSA is building. The details are classified, but experts believe it can store about 12 exabytes of data. It has cost $1.4 billion so far. Worldwide, Google has the capacity to store 15 exabytes.

1 yottabyte (YB) = 1024 B

1 zettabyte (ZB) = 1021 B

1 exabyte (EB) = 1018 B

1 petabyte (PB) = 1015 B

1 terrabyte (TB) = 1012 bytes (B)

Patrick Woods thinks Utah's NSA facility has a "reported capacity of 5 Zettabytes".

15 million vs. 5 billion terrabytes are very different estimates!
