Thank you for your response.
I am looking into the reports and the information that you have provided, I am seeing that on your drive management picture that in your D drive you have tow system partitions (EFI system and recovery system), Intel® RST is probably not giving you the option to create the RAID 0 because it is detecting those partitions, now, the situation here is that if you delete those partitions on the D driver and they are related to the OS on the C drive you may damage your OS.
In case you want to proceed to create the RAID 0, I recommend creating a backup of the data on your system before taking any actions.
You can either try deleting the partitions on D drive to have the drive to unallocated space, or you can format both drives and reinstall the OS.
