The Size and Scope of CPU and Mass Information storage

 I read over the weekend a couple articles on the amazing growth, power, and storage of our technological mediums.  As a librarian this information (sea? Ocean?—what word actually can describes numbers this big) tsunami is fascinating.  Librarians exist to help navigate this vast expanse of information, but I digress.  I will cut right to the numbers, to help slow down information growth.  The world’s total computer power currently is estimated at 6.4x10^18 instructions per second.  Or to put it in non scientific notation 6,400,000,000,000,000,000, if you lived to be 115 only 3,626,640,000 (or about 3.626x10^9 ) seconds.  Without a doubt an impressive amount of calculations per second.
 
The second number is global data storage.  This is more simply expressed at 295 exabytes, or about 1.2 billion of average sized hard drives according to the article.  Large numbers indeed.
 
But what really was fascinating is to put these in perspective.  The amount of cpu power the world is capable of producing in fact equals what the maximum number of nerve pulse 1 human brain can execute per second.  The 295 exabytes stored worldwide is not eve 1% of the information contained in the DNA of one human, in fact it is about 1/3 of 1% of the information stored in me or you.
