Which of the following describes the automatic moving of data between high-cost and low-cost storage devices?

SAN virtualization aggregates physical storage resources into a single logical pool, but it doesn't automatically move data between cost tiers.

SATA (Serial Advanced Technology Attachment) is an interface for connecting storage devices, not a data management technique.

Storage partitioning divides a physical storage device into multiple logical units, which is different from moving data between distinct storage tiers.

Hierarchical Storage Management (HSM) is a data storage technique that automatically moves data between different storage tiers, typically from high-cost, high-performance storage (e.g., SSDs) to lower-cost, lower-performance storage (e.g., tape or spinning HDDs) based on predefined policies like data age or access frequency. This optimizes storage costs while ensuring data availability.
