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. |
Drives | Two |
