Information on various types of RAID –
Data Savers Pte Ltd
RAID - Redundant Array of Inexpensive Disks, is
used to enhance the speed that the data is access and/or it’s
reliability. In a raid configuration, several hard disk drives are
connected and configured in such a way to make “one hard drive”.
There are several different kinds of RAID
configurations- here are some of the more commonly used ones:
RAID 0 (Stripe)
This configuration is used for speed and size:
two or more hard disk drives are connected in such a way that all
information is segregated into logical blocks and saved on different
hard disk drives simultaneously. The advantage of this RAID type is
that it is larger in the aspects of size and faster in the aspects
of speed. The disadvantage with this RAID type is that if one hard
disk drive becomes damaged, information on all the hard disk drives
connected to this RAID will be lost.
RAID 1 (Mirror)
This configuration is used for reliability:
usually, two or more hard disk drives are connected as such that the
similar information is saved on all hard disk drives in this RAID.
The size and speed of this RAID are the smallest and slowest hard
disk drive.
RAID 0+1 (Mirrored Stripe)
This configuration is for speed, size and
reliability: usually more than two hard disk drives are connected as
one RAID 0, and every single hard disk drive is mirrored as RAID 1.
The disadvantage to this kind RAID type is that it requires double
as many hard disk drives to get the same speed and size as in RAID
0, but in turn, it is more reliable.
RAID 5 (Stripe with Redundancy)
This configuration is utilized for speed, size
and reliability: usually more than three hard disk drives are
connected as one RAID, and one of the hard disk drives is used to
keep redundancy information. This feature (Redundancy information)
enables the ability to restore the RAID if one of the hard disk
drives is faulty.
