He says "cached write throughput", so you're absolutely right. I think the more interesting question is what the CPU utilization is relative to those speeds. Lots of operations can be sped up by feeding them more cycles, and if one driver gets e.g. 50% of the throughput with 20% of the CPU load, that could be a win depending on the application.
