And you assumed correctly. If media is *properly* supported by firmware
you have *all* rights to expect that firmware automatically picks
reasonable speed for it.

And formally you have all rights to expect that you firmware recognizes
it as 1x media. As growisofs manual page implies -speed=1 is everything
you need.

Failure to set or pick expected speed means poor media support by
firmware [or simply broken firmware].

Test several media brands and stick to one which works with your unit.
