The trade-off between data redundancy and storage capacity varies depending on the RAID level chosen. RAID levels that provide higher redundancy, such as RAID 1 or RAID 6, typically have a lower usable storage capacity due to data duplication or the overhead of parity information. On the other hand, RAID levels like RAID 0 or RAID 5 offer higher usable storage capacity but provide less data redundancy. It’s important to strike a balance between the desired level of data protection and the amount of storage space required.
