RAID 1 – Mirroring

When a logical drive is mirrored, identical data is written to a pair of disk drives, 
while reads are performed in parallel. The reads are performed using elevator 
seek and load balancing techniques where the workload is distributed in the most 
efficient manner. Whichever drive is not busy and is positioned closer to the data 
will be accessed first.

With RAID 1, if one disk drive fails or has errors, the other mirrored disk drive 
continues to function. This is called Fault Tolerance. Moreover, if a spare disk 
drive is present, the spare drive will be used as the replacement drive and data 
will begin to be mirrored to it from the remaining good drive.

Figure 2. RAID 1 Mirrors identical data to two drives.

Due to the data redundancy of mirroring, the capacity of the logical drive is only 
the size of the smallest disk drive. For example, two 100GB disk drives which 
have a combined capacity of 200GB instead would have 100GB of usable 
storage when set up in a mirrored logical drive. Similar to RAID 0 striping, if disk 
drives of different capacities are used, there will also be unused capacity on the 
larger drive.

RAID 1 logical drives on VTrak consist of two disk drives.
