HP Workstations for Linux - User Guide

Several RAID levels offer improved performance relative to a standalone disk. If the disk throughput is

lessened by a single disk controller, there is probably little you can do with RAID to improve the

performance without adding another controller. On the other hand, if the raw disk performance is the

bottleneck, a tuned software RAID solution can dramatically improve the throughput. The slower the

disk is relative to the rest of the system, the better RAID performance will scale, because the slowest

piece of the performance pipeline is being directly addressed by moving to RAID.
