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.

Features and Benefits
Drives: Minimum 2, and maximum is 2.
Uses: RAID 1 is ideal for small databases or any other
application that requires fault tolerance and minimal capacity.

Benefits: Provides 100% data redundancy. Should one drive
fail, the controller switches to the other drive.
