hi,

RAID 0 is using a mechanism called 'data striping'. It maps data across a number of different hard drives to create one large drive. The data is stored onto the physical drives in consecutive 'stripes', which are of defined size. This means that a file that is larger than the actual stripe size is distributed over the hard drives in the array, so that the different stripes of that file can be read in parallel. In this case the data transfer rate of the RAID 0 Array or 'Stripe Set' is the product of the data transfer rate of the slowest drive in the array times the number of drives that are in the array. If identical hard drives are used, the data transfer bandwidth is simply multiplied by the number of drives.
