This is required to use PMP on e.g. LinkSys WRT3200acm.

Explanation:
Generally routers like Linksys WRT3200Acm have both USB3 and eSata interfaces. To not cause Wifi 2.4GHz interference users should switch their NAS from USB3 to eSata. And this is not possible now if they have >1 HDD connected on the eSata. With 2 or more HDD over eSata required is PMP to access both/all drives. USB is different story, but Wifi 2.4GHz is unusable then.
