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.
