Maximizing Performance and Redundancy with RAID Configurations

Which RAID configuration offers both disk striping and disk mirroring?

A. RAID 0

B. RAID 1

C. RAID 5

D. All of the above

E. None of the above

Answer:

The correct RAID configuration that offers both disk striping and disk mirroring is RAID 1.

RAID, or Redundant Array of Independent Disks, offers various configurations to improve performance and provide data redundancy in storage systems. RAID 1, also known as disk mirroring, duplicates data across multiple drives to ensure data availability and protection against drive failures.

RAID 0, on the other hand, focuses on disk striping by dividing data into blocks and writing them across multiple drives to enhance performance through parallel data access. However, RAID 0 does not offer any redundancy or mirroring capabilities.

RAID 5 is a parity-based configuration that combines disk striping with distributed parity to achieve a balance between performance and redundancy. While RAID 5 provides some level of data protection through parity information distribution, it does not offer disk mirroring as RAID 1 does.

Therefore, for those looking to maximize performance and redundancy in their storage systems, RAID 1 is the ideal choice as it provides both disk striping and disk mirroring capabilities.
