title: EC2: How to tell if disk volume is instance store or EBS?
body: <p>I have a number of volumes (same size) attached to a Windows EC2 instance in Amazon AWS.</p>
  
  <p>One of them is told to be an instance store, the rest are EBS.</p>
  
  <p>How do I tell which one is the instance store? They all look the same in Device Manager - "XENSRC PVDISK SCSI Disk Device"</p>
  
  <p>PS. testing the speed did not help, one of the drives IS slightly faster than the others but how I can be sure it's an instance store?</p>
