RAID Calculator

Calculate usable storage and fault tolerance for RAID arrays

Back to Calculator Suite
How it works: Enter RAID type, number of disks, and disk size to calculate usable storage and fault tolerance. Useful for planning storage arrays.

Tips

  • RAID 0: No redundancy, max capacity
  • RAID 1: 50% capacity, 1 disk failure
  • RAID 5: N-1 disks usable, 1 disk failure
  • RAID 6: N-2 disks usable, 2 disk failures
  • RAID 10: 50% capacity, 1 disk per mirror
