Also, I guess you know that 12-CURRENT is the riskiest one to be testing 
on. You didn't mention that before :-)

Boot from an 11.2-RELEASE CD and see what it has to say.

I take what people say about computing equipment and its performance 
with a pinch of salt. would be surprised that WDs blurb says it's cheap 
blue series is faster than the enterprise versions, if anything 
manufacturers said surprised me any more. Gotta link?
