Had a thought and wanted to throw it out....I know that there will be a
'dedicated bus' for video and gigabit lan...but it seems like most of
the 'contention' in a multi-disk system is data traffic.

What I mean is this - system has a few hard-drives in it - OS / Data
(maybe on a supporting card, RAID, etc) and a few CDRom's.  Currently,
it seems that my CD-Rom's are averaging 15x (while their 'true' speed is
much higher).

While I know that a great deal of data/throughput is needed for video -
and the dedicated bus might actually make true gigabit lan a reality -
doesn't the main issue seem to be data I/O...or am I missing it?
