The interface itself matters not so much these days as the drives that 
happen to use it. Most manufacturers make both SATA and SCSI lines, are 
keen to keep the market segmented, and don't want to cannibalize their SCSI 
business by coming out with any SATA drives that are too good. One notable 
exception is Western Digital, which is why they remain the only makers of 
10K SATAs more than three years after first coming out with them.

Cheers,
Geoff
