RAID1

Data is stored into two hard disks, a data disk and a mirrored disk, in the same way.

 

Advantage:

100% data redundancy is ensured. Even if one of the two hard disks fails, it will be switched to the other hard

 

 

 

disk to continue read/write operation.

 

 

 

 

 

 

Disadvantages:

The hard disk capacity required doubles, because a mirrored disk with the same capacity is required.

 

 

 

A read/write operation during data rebuilding will result in lower performance.

 

 

 

 

 

 

 

 

 

Number of hard disks required: 2 (fixed)
