Comments:
1. FWB looks much better, doesn't it?
2. I think FWB changed read and write in the output, I can't imagine
that a driver writes faster than reads (except write cache on, don't
know if it is)
3. The number of transactions per second lowers on the Quantum drive
when switching to the FWB driver. Don't know why.
I cant see the difference to your tests, maybe Apple Germany screwed up
the formatter. I would like do testing with the original Apple HD SC
Setup.

Later Markus posted tests that compares the above with Drive Setup 1.2, which appears to improve upon HD SC Setup 7.3.5. For that post, click here.
