For those that might be wondering if the PP4 is an overall improvement, the answer is no. There is one caveat only, and that is that there is USB 3.0 functionality enabled via the PCIe bus. You can take that however you want, especially since a SATA port is next door.
Here are the formal differences in the chipsets, which differ only in their processor and memory capabilities. The 88F6192 listed first is what is in the PP4, with the 88F6281 being in plugs such as the Pogoplug v2, Dockstar, GoFlex Home/Net, and others.

Aside from those differences, everything else remains the same including SATA, GbE, PCIe, MPEG TS, Audio, CESA, USB, etc. The PP4 is essentially a step down from their original models, and of course from the oxnas variant. The good side of it all though is that they released a product once again that has mainline kernel support, and we should shortly have some information on getting ALARM installed now that the devices are in the hands of our team.
