sorry to have introduced any confusion about headedness.
in the absence of manuals, i went on what my imprimis
sales rep said.

i stand by the figure of 27MB/s for the drive under development.
although i do not understand where the nine comes from either.
perhaps just nine of the heads have i/o paths; the number nine
might be due to bandwidth considerations (how fast can IPI go?)
or from total head mass limits.

i still believe this disk to be cheapish, although with the
controller it might be as expensive as an ra81 ($15K).
