RAID Level 0
In RAID (redundant array of independent disks) storage technology, "RAID levels" are different architectures that strike a balance between performance, capacity and tolerance.
RAID Level 0 (Striped Disk Array without Fault Tolerance) provides data striping (spreading out blocks of each file across multiple disk drives), but it lacks both fault tolerance and redundancy to improve performance. As a result, if one drive fails then all data in the array is lost.
