I'm wondering how much of a difference we will actually feel. That "noticeable effect" curve has been flattening out in recent years for me. The last big jump I "felt" was going from mechanical boot drives to SSD arrays. The jump to NVME after that was barely noticeable to me in day to day real use. Certainly a jump in convenience, don't get me wrong, but boot times, gaming, etc didn't feel like a big jump for me compared to a RAID 0 SSD array.
