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 Drivers & Software
There are some known issues with NVMe disks.Please take a look at Intel® Matrix Storage Technology for more information.
