Why do we need secondary storage devices?
Secondary storage is storage for noncritical data that does not need to be frequently accessed. It trades high performance for economical long-term archiving. Data that is accessed less frequently can be migrated to secondary storage devices to free up space and improve performance on primary storage devices and lower overall storage costs.
