RAID 0
A1 A2 RAID 0 (Striping)
A3 A4
A RAID 0 (also known as a stripe set or striped volume) splits data evenly across two or
A5 A6
A7 A8 more disks (striped) with no information for redundancy. It is important to know that
once one of the hard drive fails, all of the data will be lost. RAID 0 is normally used to
increase performance, although it can also be used as a way to create a small
number of large virtual disks out of a large number of small physical ones.
DISK 0 DISK 1
RAID 1
RAID 1 (Mirroring)
A1 A1
A RAID 1 creates an exact copy (or mirror) of a set of data on two or more disks. This is
A2 A2
A3 A3
useful when read performance or reliability are more important than data storage
A4 A4
capacity. Such an array can only be as big as the smallest member disk. A classic
RAID 1 mirrored pair contains two disks (see diagram), which increases reliability
geometrically over a single disk. Since each member contains a complete copy of
the data, and can be addressed independently.

DISK 0 DISK 1
JBOD
A1 B1 JBOD (Just a Bunch of Disks)
A2 B2
JBOD is not one of the numbered RAID levels. Unlike a concatenated array, the disks
A3 B3
of JBOD appear as individual hard disks, instead of one single large disk. JBOD
A4 B4
A5
accurately describes the underlying physical structure that all RAID structures rely
A6
upon. When a hardware RAID controller is used, it normally defaults to JBOD
configuration for attached disks.

BIG / Spanning (Concatenated Array)
A1 A10 Spanning or concatenated array is also not RAID, although it is an array. It is a group
A2 A11
of disks connected together, end-to-end, for the purpose of creating a larger logical
A3 A12
A4 A13 disk. Although it is not RAID, it is included here as it is the result of early attempts to

combine multiple disks into a single logical device. There is no redundancy with a

concatenated array. Any performance improvement over a single disk is achieved

A8 because the file-system uses multiple disks. This type of array is usually slower than a
A9
RAID-0 array of the same number of disks.
