My experience doesn't agree with that, though I haven't *read* the
Google paper (I do know of it, just never got round to it).

No one said there was a magic bullet.
But 500GB IDE == $109 and 142GB SCSI == $380 isn't magic bullet
territory, and the drive adapter isn't *that* much different -- and the
build quantites are within an order of magnitude, so it's not economy
of scale, either, I don't think.
I am forced to conclude that my personal experience (SCSI drives last
longer in real, hard use) correlates with the relative pricing for a
reason, Google's research notwithstanding.
