<div class="body"><p>Many years ago, a friend of mine calculated how much it would cost
to store the sound of all phone calls in Norway, and came up with the
-cost of around 20 million NOK for all the calls in a year. I got
-curious and wondered what the same calculation would look like today.
-To do so one need an idea of how much data storage is needed for each
-minute of sound, how many minutes all the calls in Norway sums up to,
-and the cost of data storage.</p>

<p>Storage prices varies a lot, depending on speed, backup strategies,
availability requirements etc. But a simple way to calculate can be
-to use the price of a TiB-disk (around 1000 NOK) and double it to take
-space, power and redundancy. It could be much higher with high speed
-and good redundancy requirements.</p>

<p>But back to the question, What would it cost to store all phone
calls in Norway? Not much. Here is a small table showing the
and large organisations:</p>
