Hello, I just purchased an ASUS laptop equipped with a 512GB Intel SSD (Intel SSDPEKNW512GB). The read and write speeds are average. I’m thinking about swapping it for a Samsung 970 EVO Plus SSD. In the BIOS, the controller is set to Intel RST with Optane instead of AHCI by default. There’s no second drive available for Optane acceleration, which makes sense as the default. Would switching to AHCI improve performance or make it worse? I plan to reformat the system soon and wanted to ensure optimal settings regardless of the final SSD choice. Thanks!
I understand. It's good to keep the current drive. I'm curious about the RST setting—why is it enabled even without options for an RST module or RAID SSD? If I switch back to AHCI during reinstallation, should that be fine? Are there any additional drivers required for RST mode? In the Intel 3rd generation era, you could enable AHCI with RST on top, but now it seems you must pick one option.
You own an Acer Verizon X series model with serial number D18W2. When you switched it to AHCI using RST with Optane, the system stopped booting and you had to revert it back to RST with Optane. This is what happened.
