I have a PC with an NVMe SSD (Windows 10 boot drive). I installed a HDD and I opened the "Intel Optane Memory and Storage Management" software but I can't create a RAID. See screen in attachment.
Could someone please help me?
You can't create RAID array for combination of NVMe drive and SATA drive. Both drives need to be either AHCI (SATA) or NVMe (PCIe). The two technologies can't be mixed.
