RAID Level Calculator

This calculator shows the usable capacity, speed gain and fault tolerance of common RAID levels for a given number and size of disks. Enter your disks, pick a RAID level and compare the results before you build an array.

For RAID 50 and 60, “Parity RAIDs count” is the number of RAID 5 or RAID 6 groups that are striped together.
