The following images show the reading from various benchmarks. Mostly as expected, though the setting changes (Rapidmode ON/OFF) with Samsung Magician are a bit surprising.
INTEL P900 - Optane
Samsung 850 ssd - Without rapidmode
SAMSUNG 850 SSD - WITH RAPIDMODE
So the rapid mode setting made a change which seems to make a difference from even the fastest Optane, so next thing would be to find out its relevance to data processing
SanDisk ssd - external - usb 3.1
