Detailed explanation-1: -Since RAID 0 provides no fault tolerance or redundancy, the failure of one drive will cause the entire array to fail; as a result of having data striped across all disks, the failure will result in total data loss.
Detailed explanation-2: -RAID 0: This configuration is built for speed and allows you to use all of your available space. RAID 0 provides no fault tolerance. Any drive failures will cause data loss, so do not use this on a mission critical server.
Detailed explanation-3: -Nonredundant Arrays (RAID 0) An array with RAID 0 includes two or more disk drives and provides data striping, where data is distributed evenly across the disk drives in equal-sized sections. However, RAID 0 arrays do not maintain redundant data, so they offer no data protection.
Detailed explanation-4: -Data is fully redundant in a RAID 10 environment. Fast recovery. Because it does not rely on parity to rebuild any data elements lost during a drive failure or disk fails, recovering data in a RAID 10 array is fast, resulting in little downtime.
Detailed explanation-5: -RAID 0 does not use data redundancy, so the failure of any physical drive in the striped disk set results in the loss of the data on the striped unit and, consequently, the loss of the entire data set stored across the set of striped hard disks.
