RAID-10 Capacity Calculator

Calculate RAID-10 (stripe of mirrors) usable capacity: N/2 × drive_size. Combines RAID-0 performance with RAID-1 redundancy. Minimum 4 drives; survives at least 1 failure per mirror pair.

How It Works

Calculate RAID-10 (stripe of mirrors) usable capacity: N/2 × drive_size. Combines RAID-0 performance with RAID-1 redundancy. Minimum 4 drives; survives at least 1 failure per mirror pair

Each component has a specific meaning:

  • RAID-0 performance — The raid-0 performance recorded for the scenario being assessed.

Note: Interpret the raid-10 capacity result against the thresholds and context described above.

How to Use

Enter the RAID-0 performance for the scenario you are assessing. Calculate RAID-10 (stripe of mirrors) usable capacity: N/2 × drive_size. Combines RAID-0 performance with RAID-1 redundancy. Minimum 4 drives; survives at least 1 failure per mirror pair. Use the raid-10 capacity result to inform your calculation.
