I became aware of "SATA" just a couple days ago.  So that reminded me of the
multiple flavors of SCSI.

Anyway, please describe the differences between SATA and ATA.  Can SATA
drives run in Macs built for ATA?  If I want to upgrade hard drives in my
QuickSilver G4 733 in a couple years, will I need to install a new PCI card?

Many thanks,
