<title>Test the performance of your hard disk</title>
40
<p>To test the speed of your hard disk:</p>
45
<p>Open the <app>Disks</app> application from the activities
49
<p>Choose the hard disk from the <gui>Disk Drives</gui> list.</p>
52
<p>Click the more actions button next to the <gui>-</gui> button and choose <gui>Benchmark Volume</gui>.</p>
55
<p>Click <gui>Start Benchmark</gui>.</p>
58
<p>Click <gui>Start Benchmarking</gui> to test how fast data can be
59
read from the disk. If the <gui>Also perform write-benchmark</gui> option is checked, the benchmark will test how fast
60
data can be read from and written to the disk. This will take
61
longer to complete.</p>
66
<p>When the test is finished, the results will appear on the graph. The green
67
points and connecting lines indicate the samples taken; these correspond to
68
the right axis, showing access time, plotted against the bottom axis,
69
representing percentage time elapsed during the benchmark. The blue line
70
represents read rates, while the red line represents write rates; these are
71
shown as access data rates on the left axis, plotted against percentage of the
72
disk traveled, from the outside to the spindle, along the bottom axis.</p>
74
<p>Below the graph, values are displayed for minimum, maximum and average
75
read and write rates, average access time and time elapsed since the last
