RAID Calculator

RAID is an acronym for Redundant Array of Independent Disks. It’s the combining of multiple disks to mimic a single hardware storage device. Depending on your implementation, RAID can increase performance, capacity, fault tolerance, or some combination thereof.

The best RAID type for you will vary based on the use case, number of drives, and a number of other factors. Your available storage space, fault tolerance, and unused space is determined by the RAID type, number of drives, and the capacity of those drives.

Our free RAID calculator will help you determine which RAID implementation is best for you by calculating the available storage space, storage space used for protection, and unused storage space.

Our RAID calculator calculates these RAID types:

To get started using the RAID calculator, select the RAID type, select the number/capacity for the drives to be implemented, and view the results below.
