RAID Configurations Explained
What is RAID 10 and how does it differ from other RAID configurations?
RAID 10 configurations combine disk striping with disk mirroring. Which of the following RAID configurations combines disk striping with disk mirroring? a. RAID 3 b. RAID 10 c. RAID 1 d. RAID 5
Answer:
The RAID configuration that combines disk striping with disk mirroring is RAID 10. RAID 10, also known as RAID 1+0, offers a combination of RAID 1 (mirroring) and RAID 0 (striping). In RAID 10, data is first mirrored (RAID 1) and then the mirrored sets are striped (RAID 0). This approach provides both data redundancy through mirroring and improved performance through striping.
RAID stands for Redundant Array of Independent Disks, and it involves combining multiple disk drives into a single unit for improved performance, data protection, or a combination of both. RAID 10 is one of the RAID configurations that offers both data protection and performance benefits.
Unlike RAID 3, which uses byte-level striping with dedicated parity disk, RAID 10 combines disk striping with disk mirroring to provide a balance between redundancy and speed. RAID 1, on the other hand, is simple mirroring where data is replicated across multiple disks for redundancy without striping. RAID 5 uses block-level striping with distributed parity, offering a different approach to data protection and performance optimization.
Overall, RAID 10 is often considered a robust RAID configuration for businesses that require both data redundancy and improved performance. By combining disk striping and disk mirroring, RAID 10 offers the benefits of both RAID 1 and RAID 0, making it a popular choice for various applications.
