“We’re starting to hear some CTOs say, ‘Well, we don’t want to delete our data if we can mine value out of it,'” said Jake Frazier, Compliance, Governance and Oversight Councul executive director who’s also an attorney who works at IBM, in a phone interview with InformationWeek. “I think that’s a false dichotomy. Once you delete data that’s stale, the algorithms actually function much better from an analytics standpoint. Leaving stale data can actually skew the algorithms towards older facts.”

The CGOC claims that information hoarding costs enterprises thousands or even millions of dollars annually in unneeded infrastructure and storage costs, not to mention legal fees for reviewing documents that should be trashed. It also lowers productivity as workers sift through vast stockpiles of digital data to find information they need.

According to CGOC survey results, organizations on average need to archive about 2-3% of their data for legal hold, 5-10% to meet regulatory requirements, and 25% for business analysis and insights.
