Why each option
For database log drives that demand both high write performance and robust data redundancy, RAID 1+0 offers the optimal solution.
RAID 0 provides excellent performance but offers no data redundancy, meaning a single disk failure results in complete data loss, which is unacceptable for a database log drive.
RAID 1+0 (or RAID 10) combines disk striping (RAID 0) for performance with disk mirroring (RAID 1) for redundancy. This configuration provides excellent write performance, which is crucial for database log files due to their sequential write-heavy nature, while ensuring data protection against single disk failures in each mirrored pair.
