This command used for measures the performance of a storage device, to understand it we have read these type of assessment :
- A sequential or random read assessment.
- A sequential or random write assessment.
- A write flush policy test.
Syntax
winsat disk <-seq|-ran> <-read|-write> <-n <disk identification number>|-drive <drive letter>> <optional parameters>
winsat disk flush <-n <disk identification number>|-drive <drive letter>> |
| Parameter |
Description |
| -flush |
Assess disk performance in write policy flush mode. Cannot be used in combination with -seq, -ran, -write, or -read. |
