Android to Linux Distro

Thank you, Jerome, for your rapid response; I can see that I need to do a LOT of research here! I was rather puzzled by the "Linux on NAND" document; they are very negative about NAND in terms of read/write speeds. They quote read speeds in the region of 14-20MB/second. Yet, the RK3288 comes with a minimum of 8GB  of eMMC, which, presumably. it uses for critical data such as the Swap File. I note that you have expertise in the RK3188; what does that use for high-speed data storage? And how does the 14-20MB/s figure stack up against Samsung's own figures of 100-200MB/sec?
