Digital content in the average US household could reach 12 terabytes by 2014, according to researchers.

A joint report by Coughlin Associates and Objective Analysis includes DVD libraries, which accounts for a large chunk of the 12TB total.

Tom Coughlin, president of Coughlin Associates, estimates that half of the data is commercial content, like DVDs.

Making up the remaining content is user generated data, such as photos, music, and videos, and downloaded material such as video on demand.

It’s not surprising that since increasing numbers of people are downloading HD content from the likes of Netflix and iTunes this requires even greater storage capacity.

Coughlin said that the trend was also for more physical media, like DVDs and music CDs, to end up being stored on disk.

The reports suggest that key differentiators for storage vendors looking to service the home include:

  • remote storage access
  • privacy protection
  • disaster recovery
  • automatic backup
  • metadata
  • automated metadata generation of content
