Umm, for the past 5+ years or so PC SSDs have have generally been as fast or faster than what Apple has been shipping. When Apple moved to NVMe they did so before the PC industry for the most part and had some advantage but they got eclipsed.

The Neo is well below the class average.
Too often, specs or even shallow benchmarks report little more than some theoretical peak speed from system to SSD controller RAM buffers, without any real information about reads or writes that actually go all the way to the solid state storage cells. And even when they do go all the way, they fail to really highlight performance variance for different realistic workloads...
Feels fine today, but not sure how well it holds up a couple years down the line.
