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.

- Drawbacks: Requires 2 drives for the storage space of one drive.

Performance is impaired during drive rebuilds.

- Fault Tolerance: Yes.
