The Disk IO Performance grade is calculated based on the following test result metrics. Each line in the table includes the best, worst, mean and median results from all tested plans from all providers as well as the result for this particular trial.
The grade for each metric is determined based on its value in this trial compared with the same metric in all other trials and it is shown next to the value between ().
