title: Azure VM - Temporary Storage drive - a thing of the past?
body: <p>I am confused about the Azure VM setup.  I am trying to setup a SQL Server and the guidelines suggest that if your DBs are larger than 10GB, that you should setup a seperate Data Disk in Azure Storage.  But all the documentation explicitly says not to use the <code>D: Temporary Storage</code> as it is volatile across reboots.</p>
  
  <p>I completely understand this.  The issue I have is that when I create a new VM, (I just created a SQL 2012 Web on 2008 R2 SP1 <strong>from the gallery</strong>), I get a single C: drive of about 128GB.  When I then attach an empty data disk through the portal, it appears as D: and is called <code>Temporary Storage</code>.</p>
  
  <p>My understanding is that this drive is not temporary storage (volatile) as I have created it through the portal as a data disk.</p>
  
  <p>Is this a hangover from a past Azure configuration?  I gather the VMs used to come with a 30GB OS drive but now come with a 128GB OS drive.  Is this something to do with it?</p>
  
  <p>I'm pretty confused!</p>
