Thank you for posting on this Intel Community.
To better assist you, we would like to gather more information about your system.
1. Please attach an Intel® Rapid Storage Technology report.
- Open the Intel Rapid Storage Technology user interface (Start > Programs > Intel > Intel® Rapid Storage Technology).
- Click on the Help icon.
- Click on the System Report icon.
- Save the report.
2. Please run the Intel® System Support Utility (Intel® SSU) and attach the report to this thread.
- Download the Intel® System Support Utility and save the application in your computer.
- Open the application and click "Scan" to see system and device information. The Intel® SSU defaults to the "Summary View" on the output screen following the scan. Click the menu where it says "Summary" to change to "Detailed View".

The Intel RST feature can only be used with the chipset's SATA ports. I believe that, in Desktop, this is limited to six SATA ports (though Server chipsets may support more; I am unsure). While it is true that you could, using two (or three) M.2 NVMe SSDs, have a total of eight (or nine) SSDs connected to the chipset, you cannot typically mix interfaces. That is, you can create a RAID array using two (or three) M.2 NVMe SSDs and you can create a RAID array with up to six SATA SSDs, but you cannot create a RAID array using both M.2 NVMe SSDs and SATA SSDs. The one exception to this rule is that an Intel Optane Memory module, plugged into a M.2 NVMe interface, can be used, through caching, to accelerate the performance of a single SATA SSD/HDD/SSHD.
Hope this helps,
