RAID is primarily associated with which concept in network defense?

RAID, which stands for Redundant Array of Independent Disks, is a storage technology that combines multiple physical disk drive components into a single logical unit to improve data redundancy and performance. This technology is primarily utilized for data storage purposes, enabling data to be distributed across multiple disks to achieve heightened levels of fault tolerance and increased read/write speeds.

The concept of storage device virtualization is directly related to how RAID functions, as it abstracts multiple physical disks into one virtual disk. This not only enhances data availability in the event of a disk failure but also allows for easier management and allocation of resources within storage systems. Therefore, RAID effectively represents the idea of storage device virtualization by ensuring that data can be accessed and maintained seamlessly across different storage hardware setups.
