Hard drives

Paul wonders if it would be possible to build a hard drive that could hold all the information available in the world. Leo says that currently, we have hard drives large enough to hold all the information in the Library of Congress. But we really don't know how much information we really have in the world. We do know that by 2025, there will be 163 ZetaBytes (a trillion gigabytes). We're creating data at a rate of 16 trillion GB a year. The largest hard drive out there is 8,000 GB. So probably not. But that's what we have the cloud and the internet for. So users can access all that data without it being in one central location.
