Terabytes in your home

In Technology on March 28, 2006 at 2:00 pm

In Terabytes and petabytes, I wrote about the coming explosion in the amount of storage that will be available to us. A recent USA Today article contains a forecast for the amount of digital data stored on various devices in the typical U.S. household. After estimating that the typical household had about 40 gigabytes in 2004, the forecast for 2010 is 4,430 gigabytes, or 4.43 terabytes. Only a few years ago, it would have been difficult to imagine having this amount of storage in our homes.

The article indicated that this storage would be in our cell phones, MP3 players, portable video players, computers, game machines, and digital video players (DVR). DVR ownership is expected to explode. A Forrester Research vice president was quoted in a New York Times article to say that DVRs will be in 43 million homes by 2010. I imagine that these devices will account for a large fraction of the 4.43 terabytes of storage in our homes.
