I'm very surprised to see it often mentioned that NVMe M.2 vs SATA ain't noticeable. Because when I switched from a SATA to a Samsung 950 Pro (5 years ago) and latter on to a 970, it was a gigantic speed boost. The difference was, to me, very noticeable. Now I'm a software dev and do compilation and sometimes "work with files" but it's neither a server nor a simulation rig. Just a "normal software dev" setup. Now I do stuff like doing grep (well, ripgrep really) on an entire home dir, compute often hashes of files and things which may not be considered "regular use cases" but which I think are still "regular" or at least semi-regular when doing software development. To me PCIe 3.0 x4 (or now 4.0 x4 I guess) NVMe M.2 vs SATA is day and night.

Here is loading times for windows and some blind tests: https://youtu.be/V3AMz-xZ2VM https://youtu.be/V3AMz-xZ2VM https://youtu.be/4DKLA7w9eeA https://youtu.be/4DKLA7w9eeA Your personal experience could be down to several factors. For example - wear of your devices, how much your SSD was occupied, drivers, other components being updated as well, etc.

  What SATA Drive were they testing? Early SATA SSD has performance consistency problem, QD1 not as fast, etc.... they were way faster than HDD, but not perfect. NVMe started off with controller that has already been fine tuned, hence comparing them to SATA SSD tends to be a lot faster. Now if you have similar controller on NVMe and SATA you might only notice the difference in the video. But the context still matters.
