Data quality remains a problem
 
Sure, big data provides actionable insights. But what if those insights are derived from bad data? Experian reports that US organizations on average believe that 25% of their data is inaccurate. And yet 93% of the companies surveyed say data is key to their marketing success. Human error is generally the culprit here. Not only can bad data muck up marketing strategies, it can have dire consequences in more serious areas as well. Interestingly, 91% of survey respondents say they've invested in data-quality initiatives in the past year.

Surprising statistic on hard drive storage share
I found the data point that 66% of enterprise data is held on hard drives to be a surprisingly low figure. I would have thought it would have been 90%, with tape and optical dying off and Flash and RAM growing quickly. If you think about it, however, that tape and optical figure is probably much larger than one would suspect because those are highly compressed archival formats. They crunch that data down as small as they can get it and then pack it in storage media built expressly for scale. I'm guessing that accounts for the outsized data share not yet managed on HDD, but I could be wrong... Comments?

The rise of more accurate data?
It's a sad reality that so much of current data is deemend inaccurate due to user entry errors, sadly a reality, especially if you talk to marketing folks who are always cleaning up customer databases.  It will be great to see if the adoption of Big Data helps to streamline the capturing process to provide more accurate, insightful data to aid organizations in making better informed decisions.  However, sometimes too much data is a bad thing, and so the ability to sort through and really determine what data is meaningful will be the real key.
