Hi, As you said, the main difference is that persistent Images will retain the changes made when the VM is shutdown. Because of this, persistent Images can only be used by one VM at a time, while non-persistent ones can be used by several VMs.
A persistent Image will have a faster deploying time (prolog phase), depending on your storage configuration [1]. For example, for the shared TM the deployment will be immediate [2], whereas for the shared TM the deployment time will be the same [3].
