VirtualBox documentation at https://www.virtualbox.org/manual/ch05.html recommends:
Given this large choice of storage controllers, you may ask yourself which one to choose. In general, you should avoid IDE unless it is the only controller supported by your guest.

However PMM OVA appliance still uses IDE for operating system:
Use recommended SATA/SCSI/SAS for everything.
