$$$ to Store All US Phonecalls Made in a Year @ NSA Cloud so they can be Datamined

The data center is alleged to be able to process "all forms of communication, including the complete contents of private emails, cell phone calls, and Internet searches, as well as all sorts of personal data trails—parking receipts, travel itineraries, bookstore purchases, and other digital 'pocket litter'.
The Utah Data Center will gather data from intercepted satellite communications and underwater ocean cables. Analysts will decipher, analyze and store the information in order to spot potential national security threats. The facility will be heavily fortified with backup generators and powerful equipment to keep the vast computer network cool.

number of call-minutes per person per month 300 minutes (estimate from my family's usage)
sides in a phone call (caller+receiver) 2 since most calls are domestic, only need to record a call once for each reciever/caller pair
number of people in the US 315,000,000 https://www.census.gov/
number of bytes/sec in a phone call 8,000 this is the uncompressed number, could be compressed to 1/2 to 1/4 easily
cost of a Petabyte (PB) of "cloud" storage $100,000 this is basically what the Internet Archive pays. Petabyte = 1,000 terabytes
Square feet of data center space per petabyte 16 2 feet wide by about 8 feet including corridor between racks
Power to run a PB 5 kilowatts
Cost per KWhr $0.15 California costs (higher than much of the country, could be 1/2 in other places)
number of bytes/min in a phone call 480,000 calculated from above
number of bytes/month for a person 144,000,000 calculated from above
number of bytes/month for the US 22,680,000,000,000,000 calculated (divided by 2 because there is a caller and reciever, don't need to double count)
number of PB/month for the US 23 calculated
number of PB/year for the US 272 calculated
Cost to store all phone calls made in a year in the "cloud" $27,216,000
Square feet to store all phone calls 4,355
Cost of data center power for all phone calls for a year $1,788,091
