Number Calls = (330 X 10^6 People) X (3 Calls / Person / Day) = 1 X 10^9 Calls / Day
Assume each call lasts for 1 minute.
Seconds of Content = (1 X 10^9 Calls / Day) X (1 Minute / Call) X (60 Seconds / Minute) = 60 x 10^9 Seconds
Call audio data can be handled with a 4 KHz cutoff. It takes two samples per Hz to capture this data. Assume 2 Bytes per sample (actually too high).
Bytes per Day = (60 X 10^9 Seconds of Content) X (4 X 10^3 / Second) X (2 Samples) X (2 Bytes / Sample) = 9.6 X 10^14
Or, about 10^15 Bytes per Day to store raw content. One PetaByte. For perspective, this is just 1000 1 TB hard drives. The Utah facility has a capacity of about 30 ExaBytes, or 30 X 10^18 Bytes. This means that Utah could save about 30,000 days of U.S. content.
