I don't need any lessons on Nand vs. flash media, you can make yourself believe anything but the facts are very different! Below a quote from an embeded linux guy.

Speaking from a system architecture standpoint, Nand flash is directly
mapped into the CPU's memory, so has the advantage of full bus
bandwidth, at whatever the native data rate for the Nand flash is.
The sd card's speed will be a 4 bit wide data bus at best, and that's
only if they have actually implemented the 4 bit wide mode of the sd
card. Otherwise the sd card will run at a much slower rate. As it
is, the SD card will have at best, half the speed of the directly
mapped nand flash and that's only if nand flash is 8 bits wide and the
sd card is four bits wide. The relative rates only get worse from
there.
