Test the performance of your hard disk
To test the speed of your hard disk:
Open the Disks application from the .
Choose the hard disk from the Disk Drives list.
Click the more actions button next to the - button and choose Benchmark Volume.
Click Start Benchmark.
Click Start Benchmarking to test how fast data can be read from the disk. If the Also perform write-benchmark option is checked, the benchmark will test how fast data can be read from and written to the disk. This will take longer to complete.
When the test is finished, the results will appear on the graph. The green points and connecting lines indicate the samples taken; these correspond to the right axis, showing access time, plotted against the bottom axis, representing percentage time elapsed during the benchmark. The blue line represents read rates, while the red line represents write rates; these are shown as access data rates on the left axis, plotted against percentage of the disk traveled, from the outside to the spindle, along the bottom axis.
Below the graph, values are displayed for minimum, maximum and average read and write rates, average access time and time elapsed since the last benchmark test.
