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.
