Explanation
Industry Standard Architechture and Technology Rev. 9.31 Study Guide 1 of 2 - Page 265 Array Technology - Module 7 The stripe size can have the following impact: - If it is too large, poor load balancing occurs across the drives. - If it is too small, excessive cross-stripe transfers (split I/Os) occur. Split I/Os involve two disks; both disks seek, rotate, and transfer data. The response time depends on the slowest disk. Split I/Os reduce the request rate because there are fewer drives to service incoming requests.
