I develop a lot of VMs for Oracle classes (have several hundred at this time)

  • I have an external drive on which I develop VMs
  • I have an internal SATA on which I run most VMs, esp where performance is not critical
  • I run a few very important VMs on SSD

So my response is "as is normal for Oracle - it depends'.

"While I admire the idea of standards, don't let them become a ruling bureaucracy. Leave that for governments."
