What is RAID-5 volume?
Rating:
A RAID-5 volume is a fault-tolerant volume with data and parity striped intermittently across three or more physical disks. RAID-5 uses a minimum of three and a maximum of thirty-two hard disk drives. If a portion of a physical disk fails, the data that was on the failed portion can be re-created from the remaining data and parity.
RAID-5 provides data redundancy at the cost of only one additional disk for the volume, while mirrored volumes use another disk of the same disk size as that of the original data. RAID-5 volumes have better read performance than mirrored volumes.
