RAID 5

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

Recommended Applications for RAID 5

•File and Application servers

•WWW, E-mail, and News servers

•Intranet servers

•Most versatile RAID level

RAID 10

Advantages Disadvantages

Implemented as a mirrored logical drive Very high disk overhead - uses only

whose segments are RAID 0 logical 50% of total capacity drives

High I/O rates are achieved thanks to multiple stripe segments

Recommended Applications for RAID 10

•Imaging applications

•Database servers

•General fileserver

JBOD

Advantages	Disadvantages
Enables you to manage a large number	An alternative to RAID without any
of disk drives from a single controller	RAID advantages
The failure of one drive has no effect	Should not be used in mission critical
upon the data in other disk drives	environments

Recommended Applications for JBOD

•Any application requiring multiple disk drives but where read/write speed or fault-tolerance are not important

•Applications were low-cost operation critical
