RAID 0 RAID 0 provides data striping, which spreads out blocks of data over all the drives, but does not provide data redundancy.
Although performance is improved, the lack of fault tolerance means that if one drive fails, all data in the array will be lost.
RAID 1 RAID 1 provides mirroring over multiple disks, with the same read/write speed of a single disk. A RAID 1 array can only be as large as it’s smallest member disk.
Because the data is stored on multiple disks, RAID 1 provides fault tolerance and protection, in addition to performance advantages.
