About this RAID Capacity Calculator
This calculator computes RAID capacity characteristics for the most commonly used RAID types.
Provide the following parameters:
- RAID type,
- disk capacity,
- number of disks drives per RAID group,
- number of RAID groups (if your storage system consists of more than one RAID group of the
same configuration),
- single disk cost (optional) - to calculate the total storage cost and the cost per TB of
usable capacity.
To perform calculation, click Submit.
Supported RAID levels are:
- RAID 0 (block-level striping without parity or mirroring);
- RAID 1 (mirroring without parity or striping);
- RAID 1E (mirroring with striping);
- 3-Way Mirror or
Triple Mirror (mirroring without parity or striping);
- RAID 3 (byte-level striping with a dedicated parity disk);
- RAID 4 (block-level striping with a dedicated parity disk);
- RAID 5 (block-level striping with distributed parity);
- RAID 5E (RAID 5 Enhanced) and
RAID 5EE (RAID 5E Enhanced) (block-level striping with distributed parity and integrated active distributed hot-spare);
- RAID 6 (block-level striping with double distributed parity);
- RAID 10 (1+0) (striped mirrors - a combination of multiple RAID 1 groups with RAID 0);
- RAID 50 (combination of multiple RAID 5 groups with RAID 0);
- RAID 60 (combination of multiple RAID 6 groups with RAID 0);
- RAID-DP (stripe set with double parity and two dedicated parity disks);
- RAID-TEC (triple erasure encoding);
- RAID-Z1 (single parity with variable stripe width);
- RAID-Z2 (double parity with variable stripe width);
- RAID-Z3 (triple parity with variable stripe width).
