Hello, I have a been looking a solution to provide highest possible NAND Flash interface. imax8m itself having limitation to support TLC etc. 


From the application processors manual,

eMMC  => DDR mode can support up to 400 Mbytes/sec whereas raw NAND can support up to 200 Mbytes/sec. 

Looks like eMMC is faster than raw NAND. 


I am not clear on the ECC etc. Which interface(eMMC or raw NAND) will be having better throughput?
