No, it's not completely true. Many of the problems people encounter with
IDE drives are due to not enabling DMA transfers. On almost every Linux
system I've installed/used, this needed to be manually configured
(regardless of what BIOS was set to). A simple hdparm call and system and
drives were happy.
As with any bus, there are limitations with regard to bandwidth and
devices sharing that bandwidth (SCSI included) however with current IDE
buses (UDMA33 and above) this becomes more of a moot point.
