Difference between RAID 0 and RAID 1

RAID stands for Redundant Array of Independent Disk, is the technique used for disk organisation for reliability and performance. Both RAID 0 stands for Redundant Array of Independent Disk level 0 and RAID 1 stands for Redundant Array of Independent Disk level 1 are the categories of RAID. The main difference between the RAID 0 and RAID 1 is that, In RAID 0 technology, Disk stripping is used. On the other hand, in RAID 1 technology, Disk mirroring is used.
