Existing arrays can be converted to a different RAID level of equal or greater
capacity to add flexibility, redundancy or for tuning an array for a different
storage application.

overhead.
RAID 3
Some reduction in performance, lower disk
overhead.
RAID
0+1
Full redundancy instead of parity. 8 drives
required.
RAID 50
RAID 30
RAID 0
Increases capacity and performance but loses
data redundancy.
RAID 50
RAID 30
Increases performance. 6, 8, 10, 12 or 14
drives required.
RAID 3
Retains the same capacity but allows parity to
be written to only one drive.
RAID
0+1
Full redundancy instead of parity. 4, 6, 8, 10,
12 or 14 drives required.
RAID 5
RAID 0
Increases the capacity and performance but
loses the data redundancy.
RAID 50
RAID 30
Increases performance. 6, 8, 10, 12 or 14
drives required.
RAID 5
Retains the same capacity but stripes parity on
all drives
RAID
0+1
