Why each option
This question asks to identify the RAID level that combines both mirroring for data redundancy and striping for performance.
RAID 1 uses mirroring for data redundancy but does not include striping for performance.
RAID 5 uses striping with parity for data redundancy and performance, but not mirroring.
RAID 6 uses striping with dual parity for enhanced data redundancy, but not mirroring.
RAID 10 (also known as RAID 1+0) combines mirroring and striping by creating striped sets of mirrored drives. Data is first mirrored (RAID 1) across pairs of drives, and then these mirrored pairs are striped together (RAID 0), offering both high performance through striping and excellent fault tolerance through mirroring.
