Thank you for contacting Intel Technical Support.
As we understand you are using an Intel® Optane™ SSD 800P Series 58GB, M.2 80mm PCIe 3.0, 3D Xpoint to accelerate your WD Black 4TB HDD secondary/data drive and your operating system is set up on your Samsung 970 pro 512gb and you are having issue with the Samsung* magician software at the moment that you switch from AHCI to RST w/ Optane support. If we inferred correctly please review the information below:
- The Intel® Optane™ SSD 800P Series 58GB, M.2 80mm PCIe 3.0, 3D Xpoint is an SSD product and you are using it out of the specs since this device was designed for storage and not to accelerate any other drive. The Intel® Optane™ Memory products are the ones designed for this purpose and in case that you experience any problems with your product your warranty request may be denied based on your current configuration.
- A basic requirement in order to use device acceleration with the Intel® Optane™ Memory products is to have your BIOS setup to work with RST w/ Optane support.
- This issue seems to be completely related to the Samsung* magician software that does not seems to be compatible with the RST on your current configuration and we advise you to contact Samsung to get further support about this 3rd party software.
We hope you find this information useful.
Thank you for your patience and understanding.
