It's been a while since I built a system, and I just assumed I would be able to use a 64G partition on a SSD to accelerate a large mechanical SATA drive like I used to. The SSD is setup as a M.2 PCI-E device in slot 1 and the BIOS is configured to use RAID rather than AHCI. Windows 10 is booting from the SSD. Unfortunately, Intel RST doesn't seam to see the SSD, and won't let me setup SRT. Is this function reserved to Optane Memory now?
