RAID 1
In RAID 1, ADAC Ultra2 S466 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
2, 4, 6, or 8 drives.
