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.
RAID 0 arrays do not maintain redundant data, so they offer no data
protection. However, compared to an equal-sized group of
independent disks, a RAID 0 array provides improved I/O
performance.
Drive segment size is limited to the size of the smallest disk drive in the
array. For instance, an array with two 250 GB disk drives and two 400
GB disk drives can create a RAID 0 drive segment of 250 GB, for a total
of 1000 GB for the volume, as shown below.
