This is exactly the point of model-based workload synthesis! Since the oltp workload is sensitive to things like the latency of redo-log writes, it can and will intentionally perform different to a simple random I/O workload. It would be interesting to see what parts of the model showed wait-times or longer latencies -- do you have the output?
