RAID 0 or Striped Disk Array would need at least two disks in the array but treats them as a single disk drive. An operating system can combine two or more physical disks together in order to form a single logical volume in the case of normal disks to create a Striped volume.
This technique splits up the data into chunks that is written across all the disks in the array. However, the system would fill the first disk with data before going on to use the second disk. For instance, in order to produce the image of a 160 MB device, two 80 MB hard disks can be stripped.
With the simultaneous usage of multiple disks, RAID 0 delivers finer I/O performance which can be further enhanced by the use of multiple controllers, preferably one controller per disk.
Advantages:
Provides better disk transfer speed.
RAIDS 0 provides good performance in case of read as well as write operations. Parity control does not add on to overheads.
Since the entire storage capacity can be used, no disk overhead incurred.
Disadvantages:
RAID 0 is not fault-tolerant.
All data in the RAID 0 array is lost in case a disk fails.
