What's the date on that article? Because PC file sizes are already measured in terabytes. Or tebibytes, makes no matter. A cheap laptop drive these days is have a T. I don't bother setting up a machine with less than a TB drive, there's just no point, since a TB drive is about $75, and half that is $65. 2T drives are about $100.

I know I'm an outlier on the bell curve, but I have a data tank in the living room with a 6TB RAID array. But 1TB in a new machine is common.
