5.2.  SAFE (RAID 1)

SAFE mode (also referred to as RAID 1) is a secure RAID mode that 
requires at least 2 drives and works with pairs of drives (

Fig. 16

). 

One logical volume mounts on the computer and the combined 
available capacity of both drives is limited to the capacity of the 
lowest-capacity disk. If one physical disk fails, the data is available 
immediately on the second disk. No data is lost if one disk fails.

Applications

RAID 1 provides maximum data safety in the event of a 
single disk failure, but because data is written twice, per-
formance  is  reduced  slightly  when  writing.  RAID  1  is  a 
good choice when safety is more important than speed.
