Table 3-6. RAID 50 Overview
Uses
RAID 50 works best when used with data that requires
high reliability, high request rates, and high data
transfer and medium to large capacity.
Strong Points
RAID 50 provides high data throughput, data
redundancy, and very good performance.
Weak Points
Requires 2 to 4 times as many parity drives as RAID 5.
Drives
6 to 256 (Eight arrays x 32 stripes = 256 drives)
