RAID 0 vs RAID 10 Storage Capacity Calculator

Compare usable capacity, fault tolerance, and efficiency between RAID 0 and RAID 10 for NAS and homelab arrays.

Comparison Notes

This page compares RAID 0 and RAID 10 on identical hardware assumptions to help homelab builders choose between capacity efficiency and fault tolerance.

  • Disk size baseline: 8TB drives
  • Reserve policy: 10% filesystem headroom

FAQ

Can two layouts with similar storage headroom still have very different failure exposure?

Yes. Similar usable TB does not imply similar failure tolerance or rebuild exposure. Capacity and resiliency should be evaluated together.

Does RAID 0 rebuild faster than RAID 10?

Rebuild behavior depends on array width, disk size, and workload pressure. This page focuses on capacity and tolerance; benchmark your actual platform before final choice.

Which has more effective capacity: RAID 0 or RAID 10?

This NAS planning scenario compares both modes at fixed drive sizes so you can see usable capacity differences before buying disks.

How should I choose between RAID 0 and RAID 10?

Choose based on your risk tolerance, rebuild window, and performance profile. Higher parity usually lowers capacity but improves resilience.
