Suresh:
Does Mac OS has concept of write cache enabling ? Numbers below are with write cache enabled/disabled ?
Yes, OSX has write cache enabling. Presumably it's on by default (though I admit to not knowing how to confirm that), so my numbers include it. That's why I ran the test under a variety of circumstances. Benchmarks are hard, and the numbers vary a lot, so I flagged the variance. I'm not sure what all the factors are, but I believe your (implied) suspicion that cache'ing is one such factor.
