Can I add my 2c at this point? Where did 10240 appeared from? Did someone
tried to find some optimal size for most of flashes/cards? I always try to
use some large number, like 1m or even more. I know by sad experience that
writing flash with default bs can take much longer than with large bs value.
Very quick and dirty test (from dev/urandom to 1gb partition on sd card)
give me that speed numbers (bs, speed):
128m = 11,38
8m = 11,42
512k = 11,46
10k = 1,10

So, default advice on how write those images are unoptimised. Drop in speed
by factor of ten without any reason not god as for me.
