RAID 50 Arrays
A RAID 50 array is built from at least six disk drives configured as two or more
RAID 5 arrays, and stripes stored data and parity data across all disk drives in both
RAID 5 arrays. (For more information, see “RAID 5 Arrays” on page 96.)
The parity data provides data protection, and striping improves performance. RAID
50 arrays also provide high data transfer speeds.
