In fact, looking at the SATA 2.x specs, each chanell there is rated at 300MB/s, which, again, if I could 'max out evenly', could seriously blow away the SCSI bus itself ...

*If* I'm reading this right ... ?

Bus speed does not equal drive speed. And while yes, SATA is now approaching SCSI in bus speed, it doesn't mean that SCSI isn't standing still. A 640 MB/s bus was standardized in 2003 (though SATA is planned to go to 600MB/s in 2007):

This has been hashed out many times over the years in comp.periph.scsi (it used to be IDE versus SCSI, not it's (S)ATA versus SCSI). A search through the archives would probably return many results.

The SCSI FAQ [1] would also probably be useful. Specifically the questions:

QUESTION: What are the pros and cons regarding SCSI vs IDE/ATA ?

QUESTION:Should I spend the extra money on SCSI or just get IDE?

QUESTION:Why do SCSI disks cost so much more than IDE/ATA disks?
