RAID 1:
Every read and write is actually carried out in parallel across 2 disk drives in a RAID 1
array system. The mirrored (backup) copy of the data can reside on the same disk or on a
second redundant drive in the array. RAID 1 provides a hot-standby copy of data if the
active volume or drive is corrupted or becomes unavailable because of a hardware failure.
RAID techniques can be applied for high-availability solutions, or as a form of automatic
backup that eliminates tedious manual backups to more expensive and less reliable
media.
