Summary

The Avg. Disk sec/Write (PhysicalDisk\Avg. Disk sec/Write) for the physical disk has exceeded the threshold. The physical disk and possibly even overall system performance may significantly diminish which will result in poor operating system and application performance.

The The Avg. Disk sec/Write counter measures the average time of data writes on the disk.

Causes

A high Avg. Disk sec/Write performance counter value may occur due to a burst of disk write requests by either an operating system or application.

Resolutions

To view recent history for the Physical Disk\Avg. Disk sec/Write performance counter you can use the following view:

To increase the available storage subsystem throughput for this physical disk, do one or more of the following:

  • Upgrade the controllers or disk drives.

  • Switch from RAID-5 to RAID-0+1.

  • Increase the number of actual spindles.

Be sure to set this threshold value appropriately for your specific storage hardware. The threshold value will vary according to the disk’s underlying storage subsystem. For example, the “disk” might be a single spindle or a large disk array. You can use MOM overrides to define exception thresholds, which can be applied to specific computers or entire computer groups.
