A yottabyte is one septillion bytes. To save all those bytes you need a data center as big as the states of Delaware and Rhode Island. It doesn't seem like much, until they tell you the price tag: $100 trillion.
How much is $100 trillion? Too much to imagine but ,to give you some sense of scale, the gross domestic product for the United States was $14 trillion in 2008. The world's GDP: $61 trillion. And yet, one day we will look back at this figures and shrug, as we order a 4 yottabyte memory card to save a few hours of our life with our 5-senses brain impulse recording device. For $19.99.
