RAID
Concepts
RAID
is
the
abbreviation
of
Redundant
Array
of
Independent
Disks.
The
basic
idea
of
RAID
is
to
combine
multiple
drives
together
to
form
one
large
logical
drive.
This
RAID
drive
obtains
performance,
capacity
and
reliability
than
a
single
drive.
The
operating
system
detects
the
RAID
drive
as
a
single
storage
device.
RAID
Levels
There
are
various
RAID
levels
with
different
degrees
of
data
protection,
data
availability,
and
performance.
