Use JBOD with two or more disks for maximum capacity.
Use RAID 0 with two or four disks for maximum speed.
Use RAID 1 with two or more disks to mirror primary data to another disk(s) with high
performance.
Use RAID 5 with three or more disks to balance performance, hard disk capacity usage
with data protection in case of disk failure.
Use RAID 6 with four disks for more data protection in case of disk failure.
Use RAID 10 with four disks to get better performance than RAID 6, with slightly less
data protection.
See Table 8 on page 50 or Section 8.6 on page 98 for more information.
Note: Use the same capacity of hard disks for RAID 1, 5, 6, or 10 to avoid wasting space.
