RAID CALCULATOR Use RAID Calculator to determine available storage based on RAID level.
Input an estimate of the amount of storage you will need. Your available storage capacity will decrease depending on the RAID level you choose. Do not include hot spares in your raw storage calculation.
Input the amount of data you currently have in use. This will be used to generate an estimate on the number of disks you will need for this amount of available storage, after accounting for the RAID level.
