Introduction

RAID level 1 provides both very high data reliability and continued

data availability in the event of a failure of an array member. When

a RAID level 1 member disk fails, array management software simply

directs all application requests to the surviving member.

RAID level 1 is suitable for data for which reliability requirements are

extremely high, or for data to which high performance access is

required, and for which the cost of storage is a secondary issue.
