That datacenter buyers still use SCSI (and shortly, SAS) drives<br>exclusively, even over that 6:1 price disadvantage -- and the need to<br>sell it to PHBs -- tells me that the price differential exists for a<br>reason, or those guys would lose their jobs.

Admittedly if you want 15k drives you have to choose SCSI. But in terms of reliability if there was really much evidence that SCSI was better we'd be able to point to studies that show that. Instead all we've got is a lot of anecdotes.
