[NAME]  - If you look around these forums, you'll see that certain M.2 NVME SSD drivers and software won't work (or won't work well) when BIOS is set to RAID, notably those from Samsung. So you should change BIOS to AHCI before imaging the current SSD. But, you have to change it the right way or you'll end up having to reinstall Win 10 on the existing SSD: Now you're set to image the SSD and swap in the new one. BTW: I saw your other post about issues with the OEM Samsung PM9A1 SSD in your PC. If BIOS is set to RAID now, you might want to test its performance again, after you change to AHCI. Who knows, maybe you'll get lucky...
Hi! I am willing to upgrade my stock nvme SSD (Samsung PM991a 512GB) to Samsung 970 EVO Plus 1TB. My concern is that do I need to change RAID/AHCI setting upon the replacement or not necessary? PS. I will use Macrium Reflect and nvme adapter to transfer ssd data.
