Which RAID type is recommended for a high performance, write-intensive business critical
application with small random writes?

A.
RAID1

B.
RAID 1+0

C.
RAID 5

D.
RAID 6

Explanation:
Suitable RAID levels for Different Applications Common applications that benefit from different
RAID levels.
• RAID 1+0 performs well for workloads that use small, random, write-intensive I/Os. Some
applications that benefit from RAID 1+0 are high transaction rate online transaction processing
(OLTP), RDBMS temp space and so on.
• RAID 3 provides good performance for applications that involve large sequential data access,
such as data backup or video streaming.
• RAID 5 is good for random, read intensive I/O applications and preferred for messaging,
medium-performance media serving, and relational database management system (RDBMS)
implementations, in which database administrators (DBAs) optimize data access.
