The primary advantage of using a Redundant Array of Inexpensive Disks (RAID) lies in its ability to improve data access speed and provide redundancy. RAID combines multiple disk drives into a single unit, which enhances performance by allowing concurrent data access across the drives. This can significantly reduce data retrieval times, as the workload is shared among the disks.

Moreover, RAID offers redundancy, meaning that data is mirrored or striped in such a way that it remains accessible even if one or more drives fail. This ensures a level of data protection and reliability that would be lacking in single-drive configurations. Different RAID levels provide various balances of performance, redundancy, and storage capacity, making it a flexible solution for managing data effectively.

In contrast, power consumption may not necessarily be reduced with RAID configurations, whereas protection against physical attacks is typically achieved through other security measures. Additionally, using a large single disk does not offer the benefits of redundancy or performance enhancement that RAID provides. Thus, the combination of improved data access speed and redundancy stands out as the fundamental advantage of RAID systems.
