RAID 0 (Stripe)
Data is split into blocks over two or
more drives at same time for high
speed and large capacity.
RAID 1 (Mirror)
Data is written at same time to two drives only for highest level of data safety and redundancy.
RAID 10 (1+0)
Data is Striped (RAID 0) over two Mirrored sets (RAID 1) of drives
for fast redundancy.
JBOD (SPAN / N-RAID)
The physical drives are put
together without RAID to
form one logical volume.

RAID 5 (Stripe with Parity)
With RAID 5, data is striped for speed
like a RAID 0, but a duplication or parity
is built in to protect your data from
a single drive failure. This results in fast
performance comparable to a RAID 0,
but with the added benefit of protection.
RAID 5 incorporates striping of data just
like in a RAID 0 array, however, in a
RAID 5 there are redundant pieces of
the data that are also distributed across
the drives and are referred to as parity.
Having the parity blocks staggered across
each drive allows any single drive in the
RAID 5 array to fail without any data loss.
