21.5 RAID 60 Logical Drives
Similar to a RAID 50 logical drive (see RAID 50 Logical Drives), a RAID 60 logical drive—also known as dual drive failure protection—is built from eight disk drives configured as two or more RAID 6 logical drives, and stripes stored data and two sets of parity data across all disk drives in both RAID 6 logical drives.
Two sets of parity data provide enhanced data protection, and striping improves performance. RAID 60 logical drives also provide high data transfer speeds.
