Plextor M5 Pro: an other step forward

4K reads seem to have taken a bit of a hit, but not bad considering what the drive had just been exposed too.

Hmm, did you have a CPU-intensive background task (like 1 thread of Prime95) running during that AS-SSD? The 4K results look like what I see when C-states are in effect (which can be counteracted by running a background task). Do you have a "before" AS-SSD to correspond with the "after" you posted?

Sorry no, but I've seen 30 MB/s plus for 4K RR. This is one of the fastest drives I have played with.
