I'd still go for SCSI if I were you, especially now that Mark seems to be
making progress wrt to the Cumana and Powertec drivers. For them it's probably
a matter of finding a bug to get DMA transfers going while the RapIDE stuff
still needs to be developed.
But that's not the only reason. SCSI is much more expandable for a large-scale
application like a news server. People have suggested to use two 4GB drives
instead of one 9GB one and it's not difficult to hit the IDE limit some time
when you want to add more devices (not only harddisks). You will probably also
need a backup medium, how do you connect this?
Go for SCSI which is also a much more reliable thing IMHO because it's been
more properly developed and tested by many years of use. It's not uncommon to
get problems with different IDE harddisks connected to the same controller
which is much more rare for SCSI.
