	This brings me back to a question I had...  Does anyone have
numbers or theories about which combination of drive and interface
card will be the fastest....  I'm going to purchase one of these
combinations... 

	1.  RamFAST and Quantum 100
	2.  RamFAST and Seagate 80
	3.  High Speed SCSI and Quantum...

	I'm leaving out HS SCSI and seagate, because I'm assuming that
it will be the slowest...

	I was thinking the quantum and ramfast would be too expensive,
so I was debating 2 and 3...  

thanks..
