Configuring software raid – HP xw4400 Workstation User Manual
Page 24
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.
