For me, at 52, I recall the SSD transformation to be near miraculous. I never once felt that way about a CPU upgrade until getting an M1. I went from a cyrix 5x86 133 (which was effectively a fast 486) to a pentium II 266 and it just wasn't that impressive.

The drag down of swapping became almost a non-issue with the SSD changeover.

I suppose going from a //e to a IIgs was that kind of leap but that was more about the whole computer than a cpu.

Now I have to say, swapping to an SSD on my windows machines at work was far less impressive than going to SSD with my macs. I sort of wrote that off as all the anivirus crap that was running. It was very disappointing compared to the transformation on mac. On my macs it was like I suddenly heard the hallelujah chorus when I powered on.
