RAID
Level
Description
Advantage
Disadvantage
Ideal for
0
Striping.
Highest
performance.
No disk
redundancy, one
drive failure will
lose all data.
Highest
resolution
HD, 2K, and
maximum
multiple
streams.
1
Mirroring.
Highest
redundancy.
Less cost efficient
for redundancy,
loses ½ disk
capacity.
Data
protection is
paramount,
maximum
disk failure
protection.
3
Striping with a
dedicated
parity drive.
Efficient drive
redundancy, 1
drive used for
parity.
Loses 1 disk drive
capacity.
Well
balanced for
video
requiring
performance
and
redundancy.
5
Striping the
parity across
all drives.
Efficient drive
redundancy,
parity distributed
to all drives.
Loses 1 disk drive
capacity.
Well
balanced for
file server
requiring
performance
and
redundancy.
6
Striping with
two
dedicated
parity drives.
Double drive
redundancy, 2
drives used for
parity.
Loses 2 disk drive
capacity.
Mission
critical.
JBOD
Just a Bunch
of disks.
Each drive can
be accessed
individually from
operating system.
No redundancy.
