RAID 1
In RAID 1, MegaRAID Express 500 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.
