SSCP Exam - Question 112

Hierarchical Storage Management (HSM) is commonly used in very large data retrieval systems. HSM is a data storage technique that automatically moves data between high-cost and low-cost storage media in a way that ensures the most frequently accessed data is readily available on faster, more expensive media, while less frequently accessed data is moved to slower, less costly storage. This method is particularly advantageous for very large data retrieval systems, where it helps to optimize costs and performance by managing vast amounts of data efficiently.
