    <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hi all,&lt;/P&gt;&lt;P&gt;We use Alfresco as Virtual Machine (EXSi Ubuntu...). We have around 20-25 users actives. Amount of data around 800Gb. The most people use network mapping (SMB) to access to the files. We use Alfresco since 3 months and actually I had this message during peak time :&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;IMG __jive_id="14848" alt="hdd latency" class="image-1 jive-image j-img-original" src="https://connect.hyland.com/legacyfs/online/alfresco/14848_Image_90620c3.jpg" style="width: 620px; height: 125px;" /&gt;&lt;/P&gt;&lt;P&gt;And the access to files for users become slow/cannot at all.&amp;nbsp;&lt;/P&gt;&lt;P&gt;We actually use this type of HDD :&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;IMG alt="3.0 TB HDD WD NAS RED SATA-3 64 MB " class="image-2 jive-image j-img-original" src="https://www.jib.co.th/jib_content/images/gallery/WD30EFRX-RED-image.jpg" style="height: auto;" /&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;And the VM config :&lt;/P&gt;&lt;P&gt;&lt;IMG alt="VM" class="image-3 jive-image j-img-original" src="https://connect.hyland.com/legacyfs/online/alfresco/14849_Region0.png" style="height: auto;" /&gt;&lt;/P&gt;&lt;P&gt;I check all other parts as CPU, RAM and Network all are fine.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;So do I need to replace the HDD? What kind on hardware? SSD Samsung PRO 2Tb (so expensive!!) ??&lt;/P&gt;&lt;P&gt;Need expert advice please.&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Alfresco itself does not need a very specifc type of disk. The general goal would be that the disk(s) that handle the operating system, application / temp files, database files and the SOLR index have the lowest latency possible / you can provide. Using SSD for&amp;nbsp;index is a typical recommendation for best performance, as is using either a very fast disk (SSD) or sufficient memory for the database (to avoid costly IO).&lt;/P&gt;&lt;P&gt;With regards to&amp;nbsp;your specific hardware warning... I am no hardware / storage expert, so can't really say if you&amp;nbsp;have a bad HDD right there...&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
