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
- 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.
- Drawbacks: Requires 2 drives for the storage space of one drive.
Performance is impaired during drive rebuilds.
