RAID drive failure

What happens when one RAID drive fails?

When one RAID drive failure occur, all the data stored in the RAID 0 array is lost. The RAID 1 offers users more diverse use over the RAID 0. In RAID 1, you are free to store data in two locations. The first is the live dataset while the second is a mirror drive.
