RAID Arrays

Summary of RAID Configuratons
Array Uses Advantages Drawbacks #Hard Dsks Fault Tolerance
RAID 0 Non-crtcal data
requrng hgh per-
formance.
Hgh data through-
put.
No fault tolerance. multple None
RAID 1 Small databases
or any other small
capacty envron-
ment requrng fault
tolerance.
100% data redun-
dancy.
Requres 2 drves
for the storage
space of 1 drve.
2 Yes
RAID 0+1 Crtcal data requr-
ng hgh perfor-
mance.
Optmzed for both
100% data redun-
dancy and perfor-
mance. Allow spare
dsks.
Requres 2 drves
for the storage
space of 1 drve -
the same as RAID
level 1.
4+ Yes
RAID 5 Crtcal data and
reasonable level of
performance.
Fault tolerance and
better utlzaton of
dsk space.
Decreased wrte
performance due to
party calculatons.
Requres at least
three drves.
3+ Yes
JBOD Combnng odd
sze drves nto one
bg drve.
Combnes and
used the capacty
of odd sze drves.
Decreases perfor-

the dfficulty n us-
