| Disk Reads | The Disk Reads chart shows the rate at which data is being read off each disk. |

| Queue Length | The Queue Length chart shows the average number of write operations waiting to be completed for each disk. |
| Wait Time | The Wait Time chart shows the amount of time that the queue for each disk is not empty. The time is expressed as a percentage of total time. |
