HDDs

The article argues that as AI evolves, data storage becomes a critical challenge surpassing compute demands. Exponential data growth from advanced AI systems, like agentic models, necessitates efficient storage solutions, with economic factors like total cost of ownership and return on investment becoming central. Western Digital's Nicolas Frapard highlights the shift from compute-focused progress to managing vast data estates at scale.

AI infrastructure requires a multi-tiered approach, with HDDs serving as a cost-effective solution for scaling AI workloads. While flash storage offers high performance, its cost limits scalability, whereas HDDs provide proven capacity for modern data centers.
