Looks good. I've seen 9 9's mentioned in other conversations, good to have. Thanks.

The only thing to be careful about is that in order to get a solid 9 9's number, the length of run is such that the latency histograms could get fairly large. The natural quantization of the QueryPerformanceCounter is what we're relying on for the moment. Watch DISKSPD memory utilization the first few times you try to go there.
