IBM 3380 Model K introduced in 1987, has 7.5 GB of storage and costed about $160000 to $170000, or adjusted for inflation it is $455000 in 2025 US dollars, that's $60666/GB. A Solidigm D5-P5336 drive that can store 128 TB costs about $16500 in 2025 US dollars, that is $0.129/GB. That's a 470279x price reduction in slightly less than 40 years. So what is likely going to happen to LLM pricing? No one knows and both your example as well as mine doesn't mean anything.
