Shows how long since I've played with it... or needed heavy hitter  
drive performance out of a box.

You're right... when I was doing that stuff, I felt like I was a  
drive company QA tester, without the benefit of overtime pay or an  
engineer to ask dumb questions of.

Eventually I both lost interest and "found" enough "disposable"  
income to just buy faster hardware as a quick fix.  Or learned to  
live with whatever the fastest drives I could afford would do, after  
reading the results of folks willing to take the days and days  
necessary to do the benchmarks.

It was a cop-out, but time priorities have a way of forcing their  
hand better and more effectively than other priorities in life.   
Time's incessant march has a way of getting one's attention like no  
other force in the Universe, really.
