As the NUC7i5BNH was not available anymore where I live, I ordered a NUC7i5BNHX1.
The NUC7i5BNHX1 is delivered with an optane 16 Go SSD M2 memory.
As I didn’t buy yet an SSD, I tried to install ROCK on the Optane.
I confirm it works perfectly. The NUC see the Optane as a normal bootable SSD M2 Memory.
I have now few lost connection issues but I guess there is no link with the optane memory.
