(Apart from rooting/rescuing the odd phone I'm completely unfamiliar with fastboot, so sorry if this is all obvious). The main partition of a system these days is measured in GB, I think. So why does going from 32MB to 256MB for the buffer make a useful difference? Is there some enormous per-buffer overhead which needs to be amortised? Or is something else going on?
