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
¾
Drives:
Minimum 2, and maximum is 2.
¾
Uses:
RAID 1 is ideal for small databases or any other
application that requires fault tolerance and minimal capacity.
¾
Benefits:
Provides 100% data redundancy. Should one drive
fail, the controller switches to the other drive.
¾
Drawbacks:
Requires 2 drives for the storage space of one
drive. Performance is impaired during drive rebuilds.
¾
Fault Tolerance:
Yes.
