Hi, I have Samsung 950 Pro NVMe SSD on my Dell e5570 Win10. BIOS SATA settings is set to AHCI, since other modes (off, RST) leads to Windows issues or BSOD. My question is, when using AHCI for NVMe drive, is Intel's RST driver being used? Since Im seeing very inconsistent results in SSD speed benchmarks and would like to fix that. I also have Samsung NVMe driver installed. Thank You, Martin
If your BIOS is set as AHCI and the operating system was installed on AHCI mode, this is always on and the Intel® Rapid Storage driver for AHCI is running all the time.
Thank You for answering. I think OS was even installed in RST mode since it came with HDD 5.400 rpm. So my question is: Is there possibility to switch off usage of RST driver for good, and is it recommended practice for NVMe disk? Or is RST going to be fixed (when is next release coming btw?) so it does not have incosistent NVMe performance?
The only way to switch off IRST would be using IDE mode, but this will limit write and read speed.
The Intel customer support department do not have information about new driver release date, they just upload new drivers on https://downloadcenter.intel.com/ Drivers & Software
There are some known issues with NVMe disks.Please take a look at https://downloadmirror.intel.com/25165/eng/Release_Notes_14_8_PV.htm Intel® Matrix Storage Technology for more information.
