Table 1. RAID 0 Overview
Hard Drives
Required:
2-6
Advantage:
Highest transfer rates
Fault-
tolerance:
None – if one disk fails all data will be lost
Application:
Typically used in desktops and workstations for maximum performance for
temporary data and high I/O rate. 2-drive RAID 0 available in specific
mobile configurations.

2.3 RAID 1 (Mirroring)
A RAID 1 array contains two hard drives where the data between the two is mirrored
in real time to provide good data reliability in the case of a single disk failure; when
one disk drive fails, all data is immediately available on the other without any impact
to the integrity of the data.
Table 2 provides an overview of the advantages, the level of fault-tolerance provided,
and the typical usage of RAID 1.
Table 2. RAID 1 Overview
Hard Drives
Required:
2
Advantage:
100% redundancy of data. One disk may fail, but data will continue to be
accessible. A rebuild to a new disk is recommended to maintain data
redundancy.
Fault-
tolerance:
Excellent – disk mirroring means that all data on one disk is duplicated on
another disk.
Application:
Typically used for smaller systems where capacity of one disk is sufficient
and for any application(s) requiring very high availability. Available in
specific mobile configurations.

2.4 RAID 5 (Striping with Parity)
A RAID 5 array contains three or more hard drives where the data and parity are
striped across all the hard drives in the array. Parity is a mathematical method for
recreating data that was lost from a single drive, which increases fault-tolerance.
Table 3 provides an overview of the advantages, the level of fault-tolerance provided,
and the typical usage of RAID 5.
