Description: Hierarchical Storage Management (HSM) is a data storage technique that optimizes information management by automatically moving data between different levels of storage media, which vary in cost and speed. This strategy allows frequently used data to be stored on high-cost, fast-access media, such as solid-state drives (SSDs), while less frequently used data is moved to lower-cost, slower-access media, such as magnetic tapes or cloud storage. HSM not only improves storage efficiency but also reduces operational costs by maximizing resource usage. Additionally, it facilitates data recovery, as systems can quickly access critical information while archived data remains available for retrieval when needed. This technique is especially relevant in environments where large volumes of data are generated, such as in technology companies, financial institutions, and research organizations, where effective data management is crucial for performance and sustainability.
