i wouldn't think that you could tune out rotational latency.  8.4ms is
pretty much forever when you're counting nanoseconds.

since aoe can do wirespeed (120ms/s) on typical physical gige
chipsets i would think it would have no trouble keeping up with
spinning media.  especially when not handicapped by having to
actually stuff bits through a phy.
