When will SSDs be cheaper than hard drives? Based on history, it’s possible to make an educated guess, and I’m going to do it.
Back in 2011, I noticed that historical hard drive pricing fell in line pretty nicely with Moore’s Law, and predicted that SSDs would do the same. I predicted that SSDs would reach 25 cents per gigabyte sometime in 2016, and was wrong. They hit that price in 2015. So I was late by a few months.
But I’m still willing to try to predict when SSDs will cost less than hard drives. I’ll predict when they’ll hit parity too. SSDs work differently from hard drives but their pricing trend is frighteningly similar.
