If you evaluate your RAID array's performance and determine that the array is causing a bottleneck in your system, you can intelligently size additional storage capacity. Without the information that the Performance Monitor counters provide, you can only guess how much disk space you need to add to improve performance.
Adding a RAID-based disk subsystem to NT can improve a system's performance, availability, and manageability. However, you need to consider fault-tolerant support, cost, capacity, and performance when sizing RAID subsystems.
