4.5.2.8 Using Manual
Configuration: RAID 60
RAID 60 provides the features of both RAID 0 and RAID 6, and includes both parity and
drive striping across multiple drive groups. RAID 6 supports two independent parity
blocks per stripe. A RAID 60 virtual drive can survive the loss of two drives in each of the
RAID 6 sets without losing data. RAID 60 is best implemented on two RAID 6 drive
groups with data striped across both drive groups. Use RAID 60 for data that requires a
very high level of protection from loss.
