I vaguely remember reading about Linux driver a while ago, where the 
author argued that flash storage does not fit into the unix block device 
model because of erase. I've just dug up that page:

I do not suppose it to be hugely relevant to your work though, since MTD 
also relies on erase-aware filesystems.
