Arnd, I'm curious: why did you chose "3*4096" instead of "4*4096" given the previous comment? Mixing up 12MB with 12KB?
I never got around to teach flashbench about eraseblocks that have a non-power-of-two number of pages. If I do the above, there are 1024 logical "blocks" in an eraseblock, which works around this limitation, although not too well.
