RAID Level 10 combines which two RAID levels?

RAID Level 10, also known as RAID 1+0, is a combination of RAID 0 and RAID 1. This configuration takes advantage of the strengths of both levels: RAID 0 provides striping, which enhances performance by spreading data across multiple disks, while RAID 1 offers mirroring, which ensures data redundancy by duplicating the data on an additional disk.

The use of RAID 0 in this combination allows for improved read and write speeds since data is split across RAID 0's multiple drives. Meanwhile, the mirroring from RAID 1 provides a safeguard against data loss; if one drive fails, the data is still intact on the mirrored drive. RAID 10 is therefore well-suited for environments that require fast performance along with data protection, making it a popular choice for critical applications.

In contrast, the other options do not represent the correct combination. RAID 3 and RAID 5 are separate levels, each utilizing different methods for error checking and data recovery, and RAID 2 is largely outdated and not commonly used in contemporary setups. Thus, understanding the combination of RAID 0 and RAID 1 is crucial for those studying network defense and data storage solutions.
