Four years ago, I did a back of the envelope calculation on how much it would cost to store audio recordings of all the phone calls in Norway, and came up with NOK 2.1 million / EUR 250 000 for the year 2013. It is time to repeat the calculation using updated numbers. The calculation is based on how much data storage is needed for each minute of audio, how many minutes all the calls in Norway sums up to, multiplied by the cost of data storage.

[...] Both the cost of storage and the number of phone call minutes have dropped since the last time, bringing the cost down to a level where I guess even small organizations can afford to store the audio recording from every phone call taken in a year in Norway. Of course, this is just the cost of buying the storage equipment. Maintenance, need to be included as well, but the volume of a single year is about a single rack of hard drives, so it is not much more than I could fit in my own home.

    Check out the Utah Data Center [wikipedia.org]. Its storage capacity is estimated to be at least on the scale of exabytes. Probably the most relevant quote there is:

    In April 2009, officials at the United States Department of Justice acknowledged that the NSA had engaged in large-scale overcollection of domestic communications in excess of the United States Foreign Intelligence Surveillance Court's authority, but claimed that the acts were unintentional and had since been rectified.

    4 years later PRISM was leaked.
