This RAID calculator allows to compare performance characteristics of two storage systems with different RAID configurations. Supported RAID levels are RAID0, RAID1, RAID5, RAID6, RAID10 (1+0).

This calculator does not perform conversion between IO/s and MB/s, and vice versa. If you've switched the units, do not forget to enter applicable values in the Single drive performance fields.
