Performance Metrics

Analyze Test Configuration:

hdparm Timed Disk Reads

Disk To Read: /dev/sda

OpenBenchmarking.org metrics for this test profile configuration based on 522 public results since 9 February 2011 with the latest data as of 21 July 2021.

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 (hdparm Timed Disk Reads - Disk To Read: /dev/sda) has an average run-time of 2 minutes. By default this test profile is set to run at least 5 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.
