When companies or other large entities that handle large amounts of data need efficient methods of storage, they often use a tiered system of hierarchical storage based on cost. Current data that needs to be readily available can stay on modern and expensive storage for faster recovery and compliance with current technology, while data requiring long-term storage can go to slower, less expensive forms of memory. Companies do this to avoid storing large amounts of data on expensive technology, and to void transferring data each time new forms of data storage are required.
