Instance Store

Instance Store​

  • Hardware storage directly attached to EC2 instance (cannot be detached and attached to another instance)
  • Highest IOPS of any available storage (millions of IOPS)
  • Ephemeral storage (loses data when the instance is stopped, hibernated or terminated)
  • Good for buffer / cache / scratch data / temporary content
  • AMI created from an instance does not have its instance store volume preserved
note

You can specify the instance store volumes only when you launch an instance. You can’t attach instance store volumes to an instance after you’ve launched it.
