NTT and Partners Show 1 Petabit/Sec Transfer Over 50km of Fiber 59
symbolset writes "NTT and some partners, in a late paper to the ECOC 2012, show a successful transmission of 1 petabit per second data transfer over a 12-core optical fiber 52.4 km long." How long that transfer speed would take to transfer one Library of Congress's worth of data all depends on who you ask.

Every day NSA gathers 4 times the amount of data of the entire library of congress
I do not question the availability of the disk space for all those data - after all, NSA has an unlimited budget on purchasing hard disks.
But ...
How are they going to crunch all those data?
How big the machine they have to crunch at least 40 petabytes of data every-single day?
And we are not talking about simple crunching - they need to sieve through all those data to find things that are worth to keep - and then, many of those things that are worth to keep may themselves be encrypted (terrorists ain't stupid these days) - and it takes a helluva juice to decrypt all those encrypted data.
It's truly mind boggling !!

Just look at commercial institutions that do the same thing. Google, for example.
