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.
