RAID 1

In RAID 1, MegaRAID duplicates all data from one drive to a second drive. RAID 1 provides
complete data redundancy, but at the cost of doubling the required data storage capacity.

Uses

Use RAID 1 for small databases or any other environment
that requires fault tolerance but small capacity.

Strong Points

RAID 1 provides complete data redundancy. RAID 1 is
ideal for any application that requires fault tolerance and
minimal capacity.

Weak Points

RAID 1 requires twice as many disk drives. Performance is
impaired during drive rebuilds.

Drives
