Like everything silicon, I'd bet heat dissipation. As you make things more dense and thicker like that you end up needing more space just to get rid of the heat. Intel's ruler gives a better surface area to volume ratio to get rid of the heat. The 3.5" form factor (and even the 5.25") makes a lot more sense for rotating platters since those scale linearly with vertical space (or at least close to it) because they're not dissipating heat off the platters like you need to with ICs.

The Intel Ruler/EDSFF Long form factors let you devote much more of the total server volume to storage that's still accessible from the front of the machine.
