Returnal supports dualsense advanced features, you just have to plug the controller into the PC and disable steam input.
I used Returnal as the benchmark tool for the dualsense features (I don’t have a Playstation older than 2) and was amazed by them, then I realized that I didn’t like the actual game as a roguelike or a shooter so I return(al)ed it. But the controller features were sick
I thought RAID1 enabled faster reads too, because both drives have the complete file. Writes don’t get a speed bump ofc, since those are still bottlenecked by the slowest single drive in the array
