Marvell 88SE9220/9230 controller and SSD caching

[MARSTG]

It is the Marvell 88SE9220 controller responsible for the new "Asus SSD Caching II" marketing gimmick but are there any standalone products based on this controller? As in add in cards?
Edit : I found there is one for sale already on newegg a SYBA SY-PEX40052 that has 2 sata III ports and model PEX40053 has one SATA and one mSATA ports. So this would allow the famous SSD Caching to also happen on other platforms than just Intel, (namely AMD), and even on older Intel platforms. Anyone got it?

I have a P8P67 Deluxe. I tried the Asus caching and yes it did work. That said I am not confident in the Marvell controller on the whole. While using it my system experienced instability that I otherwise did not while using the Intel controller. Just saying.
