I'm quite surprised with data sizes mentioned in the article, and wondering if I'm missing something...We are a very small 2yo company, handling route optimization and delivery management / field service. Even with our very small number of customers, their relatively small sizes (e.g. number of "tasks" per day), being very early in development in terms of data that we collect - our database containing just customer data for 2 years is ~100GB. Which I previously considered small, and if we collected useful user metrics, had more elaborate analytics, location tracking history etc, I would expect it to be at least 3x.

We don't use any "BigData" products yet, as there wasn't any need for them, even when we provide full search and relatively nice and rich set of analytics over all the data. Yet, based on the article, we're way above most of the companies relying heavily on such tools. Confusing.
