Most of the time when unstructured data is created there is never a need to access it again. But it is still necessary to store it just in case you need it. When the “just in case” scenario occurs, you need to retrieve it quickly and it has to be readable. The problem is that “just-in-case” may occur at anytime, from a few days after someone creates the data, to a few decades later. The storage system has to be able to store this data efficiently for a long period of time. The need for long term data efficiency is one of the reasons why network attached storage systems are giving way to object storage systems.9
