Buffering also allows the device to write the data in bursts, which
makes the write(s) orders of magnitude faster in most cases; and it also
allows the device to write in sequentially large chunks, instead of
simply writing the data as its received, which allows for things like
I/O scheduling and prioritizing, et al.
