I think very unlikely - the best I have got on iozone on my RockPro64 is around 30MB/s (and 65MB/s read). Allegedly the eMMC is 150MB/s read on the PPP. Of course all is up for grabs until we get real world results.
I did a quick search for RK3399 bus details and came up empty handed (it was v quick). But makes sense anything fast is linked to the eMMC and the SDcard, as per the RockPro64, could be the poor relation. Then again the PPP doesn't have SPI nor PCIe so maybe the SDcard gets a boost. But as it looks like the same physical carrier to the PinePhone I wouldn't hold my breath.
