How To Choose

Guide Safety First

Recommended: RAID 1/6/10 or RAID-Z2/Z3 when data safety is the highest priority.

Guide Perf First

Recommended: RAID 0 or RAID 10 for high-throughput, low-latency workloads.

Guide Balance

Recommended: RAID 5 or RAID-Z1 for a balance of capacity, performance, and cost.

Guide Enterprise

Recommended: RAID 6, RAID 10, or RAID-Z2/Z3 for mission-critical and large-scale deployments.
