… The US alone is home to 898 exabytes (898 billion gigabytes) – nearly a third of the global total. … Western Europe has 19% and China has 13%. Legally, much of that data itself is property of the consumers or companies who generate it, and licensed to companies that are responsible for it.
The most recent data on who’s storing that data are from 2009, and published in a report released by the McKinsey Global Institute. Although this may have changed some in the last few years, it’s our best guess yet about who actually holds onto a lot of US data.
