RAID 0
RAID 0 divides data into block units and writes them in a dispersed manner across multiple disks.
As data is placed on every disk, it is also called "striping".
This process enables high level performance as parallel access to the data on different disks improves speed of retrieval. However no recovery feature is provided if a disk failure occurs.
If one disk fails it effects both reads and writes, and as more disks are added to the array the higher the possibility that a disk failure will occur.
