You may use this intuitive tool to calculate the usable storage capacity, fault tolerance, and performance for various RAID levels, including RAID 0, 1, 5, 6, 10, Nested RAID 50 and 60, and ZFS RAID levels Z1, Z2, and Z3. Detailed descriptions of each RAID type highlight their advantages, limitations, and optimal use cases. This tool is still a work in progress but should be mostly accurate.
