| Here's an article from 2011 doing Moore's Law extrapolation of RAM and disk prices: https://antranik.org/using-moores-law-to-predict-future-memo... RAM, 2011:
"A single 8GB stick of RAM is about $80 right now. In 2021, you’d be able to buy a single stick of RAM that contains 64GB for the same price." Disks, 2011:
"The price of a 1-terabyte hard drive is $80 now... In 2013, a 2TB drive will be $80. In 2015, a 4TB drive will be $80. After that the doubling rate may lengthen to 3 years instead of 2 years so.. In 2018, an 8TB drive will be $80. And finally in 2021, for $80, you’d be able to buy a 16 terabyte hard drive" |
Certainly for consumer hard drives, there’s a cost of getting the drive to the customer (transport, shop rent, employee salaries, etc) which is, at best, fixed.
If manufacturing costs drop to zero, price will approach that fixed cost (plus any markup sellers manage to extract, for example by marketing their drives as better/more hip/etc.)
