I've done a bit of testing with the Intel units: S3600, S3700, S3710, and
P3700. I've also tested the Samsung 850 Pro, 845DC Pro, and SM863.
All of my testing was "worst case IOPS" as described here:

That's pretty good result, isn't it?
I guess you've been tuning your cluster??

We replaced 32 S3500s with 48 Micron M600s in our production cluster. The
S3500s were only doing journals because they were too small and we still
ate 3-4% of their life in a couple of months. We started having high wait
times on the M600s so we got 6 S3610s, 6 M500dcs, and 6 500 GB M600s (they
