The Real Reason Hadoop Is Such A Big Deal In Big Data – ReadWrite

Back to data basics

"Sometimes the reasons behind something success can be staring you right in the face. For Hadoop, the biggest motivator in the market is simple: Before Hadoop, data storage was expensive.
Hadoop, however, lets you store as much data as you want in whatever form you need, simply by adding more servers to a Hadoop cluster.

This makes data storage with Hadoop far less costly than prior methods of data storage."
