It’s so consistent it has a name:
Moore’s law is the observation that the number of transistors in an integrated circuit (IC) doubles about every two years.

Quick note, HDD storage is not using transistors to store the data, so is not really directly related to Moore’s law. SSDs do use transistors/nano structures (NAND) for storage and it’s storage capacity is more related to Moore’s law.

I heard that we were at the theoretical limit but apparently there’s been a break through: https://phys.org/news/2020-09-bits-atom.html
