Transfer rates with NAND

[Indrek Kruusa]

Hi,

I am wondering which NAND transfer rates are seen in embedded Linux 
projects. What to expect from the whole hardware/software subsystem?
I have one Geode LX design with CS5536 companion chip which by using 
built-in 8-bit Flash controller on PCI bus gives me slightly over 2MB/s. 
It's almost the same with Linux MTD driver and with a self-made basic 
driver. Is the speed here the matter of flash controller only? Which is 
the fastest flash controller out there? :)

thanks in advance,
Indrek
