If we use hardware with very small RAM (let's consider just a couple of hundreds of kB but not megabytes) it is not super convenient to lose 64kB for statically allocated bufer which most probably won't be used as big as it is. Typically we'll have much shorter data packages to excahnge and in the worst case longer packets will be split on separate transactions.
