I remember the first time I heard that a one gigabyte hard drive was coming to store shelves. My Dad and I spent a good 20 minutes wracking our brains trying to think how anyone could possibly fill up that much space.
As we soon found out, the more space you have, the more information appears to fill it. For a business that generates gigabytes of information every second, and has to store it for years and years, that's especially true. It's one reason companies like Amazon offer businesses massive amounts of storage for relatively little money.
Now Google is getting into the game with Google Cloud Storage Nearline, which offers storage space at a cost of one cent per gigabyte per month. To entice businesses to join, Google is even offering 100 petabytes of storage for free, which would normally cost $1 million dollars a month.
Just so we're clear, 100 petabytes is equal to 100,000 terabytes or 100 million gigabytes. In real-world terms, 100 petabytes could store around 1.6 million HD movies or 10 billion high-quality photo images. Yep, you could store a single photo of every person alive on the planet, and still have room left over.
