Since iscsi is the transport protocol, would it make sense to append iscsi to the disk type, like iscsi-hdd or iscsi-ssd? (I have not used iscsi so this may be a dumb question).

I don't think the iSCSI protocol exposes the backend device type. But I'll try an experiment with both backends to see if we can see it. If so then a hybrid might make sense.

Motivation and Context
In the

Added support to the
mediascript to detect if a device is iSCSI.How Has This Been Tested?
manually tested with a pool comprised of iSCSI devices. Here are two example runs with the new detection:
