Changing the Fault Tolerance Mode
Performance decreases in this order:
■
RAID 0 (highest performance, but no protection against drive failure)
■
RAID 1
■
RAID 5
■
RAID ADG
If performance is too low with your current fault tolerance method, it can be
improved by migrating to a different RAID level. Follow the steps outlined in
the section “Migrating an Existing Logical Drive to RAID ADG” earlier in
this chapter, and select a different RAID level at the appropriate step in the
sequence.
