<p>This should say why a user might want to do this.</p>
35
<p>We shouldn't call the emblem-system-symbolic "gear icon", but there's
36
not a much better alternative.</p>

39
<p>To test the speed of your hard disk:</p>
34
<p>Open the <app>Disks</app> application from the activities
38
<p>Choose the hard disk from the <gui>Disk Drives</gui> list.</p>
41
<p>Click the gear button and select <gui>Benchmark Drive</gui>.</p>
44
<p>Click <gui>Start Benchmark</gui> and adjust the <gui>Transfer Rate</gui>
45
and <gui>Access Time</gui> parameters as desired.</p>
48
<p>Click <gui>Start Benchmarking</gui> to test how fast data can be read from
49
the disk. <link xref="user-admin-explain">Administrative privileges</link> may
50
be required. Enter your password, or the password for the requested administrator
53
<p>If <gui>Also perform write-benchmark</gui> is checked, the benchmark
54
will test how fast data can be read from and written to the disk. This will
55
take longer to complete.</p>
43
<p>Open the <app>Disks</app> application from the <gui>Activities</gui>
47
<p>Choose the hard disk from the <gui>Disk Drives</gui> list.</p>
50
<p>Click the gear button and select <gui>Benchmark Drive</gui>.</p>
53
<p>Click <gui>Start Benchmark</gui> and adjust the <gui>Transfer
54
Rate</gui> and <gui>Access Time</gui> parameters as desired.</p>
57
<p>Click <gui>Start Benchmarking</gui> to test how fast data can be read
58
from the disk. <link xref="user-admin-explain">Administrative
59
privileges</link> may be required. Enter your password, or the password
60
for the requested administrator account.</p>
62
<p>If <gui>Also perform write-benchmark</gui> is checked, the benchmark
63
will test how fast data can be read from and written to the disk. This
64
will take longer to complete.</p>

<p>When the test is finished, the results will appear on the graph. The green
62
points and connecting lines indicate the samples taken; these correspond to
63
the right axis, showing access time, plotted against the bottom axis,
64
representing percentage time elapsed during the benchmark. The blue line
65
represents read rates, while the red line represents write rates; these are
66
shown as access data rates on the left axis, plotted against percentage of the
67
disk traveled, from the outside to the spindle, along the bottom axis.</p>
70
points and connecting lines indicate the samples taken; these correspond to
71
the right axis, showing access time, plotted against the bottom axis,
72
representing percentage time elapsed during the benchmark. The blue line
73
represents read rates, while the red line represents write rates; these are
74
shown as access data rates on the left axis, plotted against percentage of
75
the disk traveled, from the outside to the spindle, along the bottom
69
78
<p>Below the graph, values are displayed for minimum, maximum and average
70
read and write rates, average access time and time elapsed since the last
79
read and write rates, average access time and time elapsed since the last
