workload is more random in Nature, then the bottleneck is likely to involve the disk drives, and adding more drives will Improve performance. If the workload is sequential and the bandwidth pressure of the controller is high, the solution is to add a faster disk controller; If the workload is random, the bottleneck may be the hard drive. increasing the driver can improve the performance; . Add more disk d
