      <description>&lt;!-- [DocumentBodyStart:e2613182-2450-4724-9c36-a20e08109114] --&gt;&lt;div class="jive-rendered-content"&gt;&lt;p&gt;Thanks Peter.&lt;/p&gt;&lt;p style="min-height: 8pt; height: 8pt; padding: 0px;"&gt;&amp;nbsp;&lt;/p&gt;&lt;p&gt;In total it took 35 hours without write back cache.&lt;/p&gt;&lt;p style="min-height: 8pt; height: 8pt; padding: 0px;"&gt;&amp;nbsp;&lt;/p&gt;&lt;p&gt;Just for anyone interested, I tested the raid array (32kb stripe) after the initialization using ATTO disk benchmark 2.34 in windows 7 x64 (64kb NTFS cluster)&lt;/p&gt;&lt;p&gt;With write back cache ON: write speed was consistently around 70MB/s and read was between 150 - 210MB/s&lt;/p&gt;&lt;p&gt;Turn write back cache OFF: Write speed peaked at 90MB/s for 64KB files, and lowered to 30MB/s for 8MB files (and only 900KB/s for 0.5 KB files) , while read speed was same as with write back cache ON (150-210).&lt;/p&gt;&lt;p style="min-height: 8pt; height: 8pt; padding: 0px;"&gt;&amp;nbsp;&lt;/p&gt;&lt;p&gt;So if you have a stable OS then turning write back cache ON seems to give a good overall speed boost.&lt;/p&gt;&lt;/div&gt;&lt;!-- [DocumentBodyEnd:e2613182-2450-4724-9c36-a20e08109114] --&gt;</description>
