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
|
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
File and Application servers
Database servers
Web, E-mail, and News servers
Intranet servers
Most versatile RAID level
