Nice comparison. It might also be interesting to adjust everything for inflation. That might seem odd, but it would allow for a price-adjusted comparison.
Let's look at the Geekbench score and adjust for 2025 dollars.
2009: 302 / 1491 = 0.203 'geeks' per 2025 dollar
2025: 2605 / 1000 = 2.605 'geeks' per 2025 dollar
That's a 12.86X per dollar improvement (up from 7.63X).
RAM
2009: 2 / 1491 = 0.001 GB per 2025 dollar
2025: 16 / 1000 = 0.011 GB per 2025 dollar
That's a 11.928X per dollar improvement (up from 7X).
Storage
2009: 250 / 1491 = 0.168 GB per 2025 dollar
2025: 256/1000 = 0.256 GB per 2025 dollar
That's a 0.65X per dollar improvement (up from 0.024).
That's still an outlier, but the technology completely shifted for storage (as your read/write metrics show). The storage can also be used as a slower but still relatively quick alternative to RAM (swap) when needed. That was true on systems back in 2009, but swap was
really slow. This means capacity is only part of the story. While storage capacity appeared to stagnate, storage capability drastically improved.
That idea is also clear from the processor speed comparison. GHz doubled, but due to more cores, the actual performance (at least on benchmarks) increased dramatically. Think of the storage as doing something akin to adding more CPUs/cores.
Also, let's say storage increased the same as RAM -- I'll do both 7X and 12X increases. That would be the base model Air having a 2 or 3 TB SSD. Could Apple include that? Yes. And keep the base price $1000? Maybe, but there would be much smaller margins and profitability.
Storage needs are not that high for most people. That's not an excuse, it's simply reality with so much being 'cloud' based now.
