Understanding stripe-unit size W ith RAID technology , data is striped across an array of physical drives. This data-distribution scheme complements the way the operating system requests data. The granularity at which data is stored on one drive of the array befor e subsequent data is stored on the next drive of the array is called the stripe-unit [...]

workloads are steady and sequential. However , if the workload is random or the system I/O requests ar e smaller than the stripe-unit size, reading ahead to the end of the stripe might degrade performance.
