Regardless where demand comes from, it takes time to spin up a hard drive factory, and prices would have to rise enough that, as a producer, you would feel confident that a new hard drive factory will actually pay off. Conversely, if you feel that boom is irrational and temporary, as a producer you’d be quite wary of investing money in a new factory if there was a risk it would be producing into a glut in a few years.
