Performance Metrics

Analyze Test Configuration:

Diskspd 2.0.21

Threads Per Target: 1 - Write Requests (Percent): 100 - All Writes - File Size: 1M - Block Size: 4KB

OpenBenchmarking.org metrics for this test profile configuration based on 97 public results since 11 March 2019 with the latest data as of 29 December 2020.

Below is an overview of the generalized performance for components where there is sufficient statistically significant data based upon user-uploaded results. It is important to keep in mind particularly in the Linux/open-source space there can be vastly different OS configurations, with this overview intended to offer just general guidance as to the performance expectations.

Based on OpenBenchmarking.org data, the selected test / test configuration (Diskspd 2.0.21 - Threads Per Target: 1 - Write Requests (Percent): 100 - All Writes - File Size: 1M - Block Size: 4KB) has an average run-time of 45 minutes. By default this test profile is set to run at least 3 times but may increase if the standard deviation exceeds pre-defined defaults or other calculations deem additional runs necessary for greater statistical accuracy of the result.
