•
RAID 1 (drive mirroring):
Data is written simultaneously
to both drives in the drive group, providing complete data
redundancy if one drive fails. RAID 1 supports an even
number of drives from 2 to 32 in a single span.
•
RAID 5 (drive striping with distributed parity):
Data is
striped across all drives in the group. Part of the capacity
of each drive stores parity information that reconstructs
data if a drive fails. RAID 5 provides good data throughput
for applications with high read request rates.
•
RAID 10 (RAID 1 and RAID 0 in spanned groups):
RAID 10 uses mirrored pairs of drives to provide complete
data redundancy. RAID 10 provides high data throughput
rates.
Note:
