<h1> RAID levels that can use a hot-spare drive</h1>
<p>Hot-spare drives supply additional protection to a RAID configuration. When
  you select the RAID level for your configuration, consider the following:</p>
<table width="55%" border="1" align="center" cellpadding="3">
  <tr valign="top" bgcolor="#C0C0C0">
    <td width="24%"><b>RAID level</b></td>
    <td width="38%"><b>Can use a hot spare?</b></td>
  </tr>
  <tr valign="top">
    <td width="24%">0</td>
    <td width="38%" align="center">No</td>
  </tr>
  <tr valign="top">
    <td width="24%">1</td>
    <td width="38%" align="center">Yes</td>
  </tr>

  <tr valign="top">
    <td width="24%">5</td>
    <td width="38%" align="center">Yes</td>
  </tr>
<tr valign="top">
    <td width="24%">6</td>
    <td width="38%" align="center">Yes</td>
  </tr>


  <tr valign="top">
    <td width="24%">10</td>
    <td width="38%" align="center">Yes</td>
  </tr>

  <tr valign="top">
    <td width="24%">50</td>
    <td width="38%" align="center">Yes</td>
  </tr>

  <tr valign="top">
