You have to be careful with Tom's IOMeter data. Some of the data in their reviews is labeled as QD1, but it really is not (for example, they give 100+ MB/s 4KB QD1 reads, which is absurd). I think the problem is that they set IOMeter for QD1 but also start up 4 or 8 or more worker threads. Each worker thread may only let one IO queue up, but since the worker threads are submitting IOs in parallel, the queue fills up higher than 1 anyway. I think the only thing that should be labeled QD1 is when there is only one worker submitting IOs, and it limits its queue depth to 1.
