Highest Read data transaction rate
Medium Write data transaction rate
Low ratio of ECC (Parity) disks to data disks means high efficiency Good aggregate transfer rate Most versatile RAID level.
Disk failure has a medium impact on throughput. Most complex controller design.
Difficult to rebuild in the event of a disk failure (as compared to RAID level 1)
Individual block data transfer rate same as single disk
