I cool my server to 30°-35° HDD temperatures, because that's supposed to increase their life. However, all my SSDs are then at 23-27° [1]. I think I saw some long endurance tests and they pointed out that failure rates for SSDs increase slightly below 25°. Tricky tradeoff.

HDDs and SSDs operate on fundamentally different technologies, so it shouldn't be a surprise that they desire vastly different environments to reside in.

  I would think that over many years of iteration by engineers, both would converge on functioning reliably in the same environment. They're both intended to be integrated into computer systems after all.

    They do operate reliably in the same environment; what you're talking about is operating in ideal environments. When we're talking ideals, it shouldn't come as a surprise that two fundamentally different things desire two fundamentally different ideal environments.

      I appreciate your distinction, but I still think my point stands. As the technology is iterated on and refined based on years of feedback from real world use, I would expect the ideal environment for a given class of technology to converge on the typical operating environment. Decisions will be made that shift the physical properties one way or another. Silicon will be doped with different impurities. Transistors will be made with different sizes and geometries. Different metals and plastics will be used. Different voltages will be applied. People desire practical technological solutions to serve their needs. A box of "spinning rust" doesn't desire much of anything. A CPU is just a rock that's better at arithmetic than another rock.

Yeah, it's interesting because I think some parts of the SSD want cooler temperatures but writing to the flash might actually do less damage to the cells if you're writing at higher temperatures (higher charge mobility in silicon).
