I'm thinking the reason you can't repeat the test may be latency
related. We get ~50usecs average latency (on small block sizes),
which can't be achieved using regular SSD's (and rotating drives are
nowhere close). Maybe a ramdisk would help repeat the issue.
I think you should try to reproduce the problem with ramdisk or nullio.
By so you will eliminate possible influence of the SSD backend.
