Using the Advanced RAID Calculator you can see the exact amount that your array will have using any size of Hard Disk.
ARC Supports the following RAID Levels:
0, 1, 3, 3+0, 4, 5, 6, 0+1, 1+0, 1+0+0, 5+0, 5+1, 6+0, 6+1, BeyondRAID, unRAID, X-RAID, RAID-Z, RAID-Z2, RAID-Z3, RAID DP.
The app also provides an IOPS calculator to find the type of disk required to achieve the IOPS in the backend as well as a power requirement calculator to help in selecting the appropriate PSU for your setup.
It currently has an extensive database of HDD's but you can also add 1 custom disk with your own specs.
