I understand you would like to know if the Intel® NUC Kit NUC7i3BNK supports Legacy SATA and PCI Express using NVMe logical device interfaces and command sets simultaneously.
Let me apologize for any inconvenience this issue may be causing to you.
Let me do some research about this and come back to you.
I will post information on this forum thread as soon as I have it available.
