RAID 1E

Advantages	Disadvantages

Implemented as a mirrored disk array	Very high disk overhead - uses only
whose segments are RAID 0 disk	50% of total capacity
arrays
High I/O rates are achieved thanks to
multiple stripe segments
Can use an odd number of disks

Recommended Applications for RAID 1E

•Imaging applications

•Database servers

•General fileserver

RAID 5

Advantages	Disadvantages

High Read data transaction rate	Disk failure has a medium impact on
Medium Write data transaction rate	throughput
Medium Write data transaction rate
Good aggregate transfer rate

Recommended Applications for RAID 5
• File and Application servers	• Intranet servers
• WWW, E-mail, and News servers	• Most versatile RAID level

RAID 10

Advantages	Disadvantages

Implemented as a mirrored disk array	Very high disk overhead - uses only
whose segments are RAID 0 disk	50% of total capacity
arrays
High I/O rates are achieved thanks to
multiple stripe segments

Recommended Applications for RAID 10
