johnodon Posted September 24, 2012 Author Share Posted September 24, 2012 How full are these drives, that can provide a significant skew in the benchmarks.

I am going to revert backwards through the RCs/betas and see if I start to see an increase in write speed. I need to wait for my parity sync to finish first. John Quote Link to comment
