<title>测试硬盘性能</title>

  <p>测试您的硬盘的速度</p>

  <steps>
    <item>
      <p>Open <app>Disks</app> from the
      <gui xref="shell-terminology">Activities</gui> overview.</p>
    </item>
    <item>
      <p>Choose the disk from the list in the left pane.</p>
    </item>
    <item>
      <p>Click the gear button and select <gui>Benchmark…</gui> from the
      menu.</p>
    </item>
    <item>
      <p>Click <gui>Start Benchmark…</gui> and adjust the <gui>Transfer
      Rate</gui> and <gui>Access Time</gui> parameters as desired.</p>
    </item>
    <item>
      <p>Click <gui>Start Benchmarking</gui> to test how fast data can be read
      from the disk. <link xref="user-admin-explain">Administrative
      privileges</link> may be required. Enter your password, or the password
      for the requested administrator account.</p>
      <note>
        <p>If <gui>Perform write-benchmark</gui> is checked, the benchmark
        will test how fast data can be read from and written to the disk. This
        will take longer to complete.</p>
      </note>
    </item>
  </steps>

  <p>测试完成后，将会显示测试结果图表，绿色的点和线段代表样例，它们与右边的纵轴线相对应，显示访问时间，与底部横座标轴线组成小方格，对应花费的时间百分比。蓝线代表读取速率，有红线代表写入速率，在左侧的纵轴上显示了访问速率，与底部横座标轴线组成小方格，从外到内，对应磁盘访问的百分比。</p>

  <p>图像下方将显示最大、最小和平均读写率等多个指标的数值。</p>
