It's only a hypothesis, but you would have to know the rough size of the CMR/cache partition on the SMR drive. Blasting it with small, random I/O would cause the drive to write it to the cache partition, once that fills up then you'll have to write straight to the SMR portion and that's when you should see the latency spike.
Maybe I'll have to get one of these smaller SMR drives and expose the scenarios where they fall down.
