> NVMe While NVMe benchmarks are stunning I really am curious whether in an ordinary setting the difference to SATA can be felt at all. Not measured -- felt. When the era of swap ended because CPUs / chipsets finally could handle enough RAM and when we went from HDD to SDD, those could be felt for sure. > This is marginally different for laptops In laptop world, the problem is that with the spread of thin craze most laptops are now running 15W CPUs instead of 35W like in the old age and so there is little performance increase, no core count increase.

I switched from a 2012 15'' MacBook Pro to a 2017 15'' Macbook Pro and the difference is staggering. The older laptop had a regular SSD, while the newer one is using NVMe. Although it also has a considerably newer CPU, which likely plays a huge role in the performance difference. I sometimes tweak stuff on both laptops at the same time, and doing a side-by-side restart or even waking up from sleep makes the older model's lesser performance painfully obvious

  Additionally "thin craze" matters - I remember having an old 15" laptop in the mid/late '00s that would actually give me backache after carrying it in my backpack for a while. Today I can't even tell if my 13" dell xps is in it or not.

    Interestingly, I cannot really tell if the notebook is in the backpack, but a water bottle with about the same total weight can totally be felt. Probably the very beneficial weight distribution of a flat slab that's affixed in an upright position directly against my back, vs. a cylindric bottle that's either moving around in the backpack, or stuck to its side and therefore exerting a sideways torque on my back.

As you say, the thinness craze was enabled by lower-power CPUs that performed no worse than previous gens. They need smaller batteries and less extreme cooling which means smaller sizes. Alternatively, keep the same size and you can enlarge the battery. Either way, perf/watt gains have enabled that in a way that's visible to consumers. With a plugged in PC, that's not visible.

Last year I went from a Corsair Neutron 240GB to a Samsung 950 Pro. Not much difference in daily usage under Windows 7.

NVMe definitely feels faster. I have an NVMe and a SATA SSD in my workstation. I do most of my work off the NVME, but occasionally work on projects that live on the SATA disk. I definitely notice a difference in things with a lot of disk access.

  About the only things I've noticed is in some of my node projects so far.. for general use, not nearly so much.

Just upgraded to an NVMe for my primary drive... my mb had a x2 nvme slot, but it didn't work... luckily I got a pciex4 adapter, frankly, I know it's a bit faster than the SSD, but in general use, I haven't noticed the difference so much. Aside from node builds are a bit faster (which tends to touch a lot of random files on disk). General use hasn't been noticeable.
