Well, I have been known to rip data from DVD's to my hard drive, from time to time, for backup of course. When I do, my CPU utilization goes into orbit with my current IDE DVD drive; and I have a dual Athlon MP2000 system.
I think you had it right, I was looking for both a scsi CDRW and scsi DVD-ROM separately.
Thanks for the link to that other thread mcveigh. Sad about Yamaha passing of an IDE drive as scsi; the search continues I guess. I thought there would at least be a niche market for scsi CDRW and scsi DVD-ROM's beyond single digit speed ratings.
edit: I just checked again and the cup util. is only about 53% during ripping, both cpu's. Still, I notice the slowdown.
