Western Digital argues AI's longer payoff lies in stored data, not compute

Western Digital argues that demand for hard drives depends less on the current wave of AI spending than investors fear. On its fiscal first-quarter earnings call on October 22, the company said demand for disk storage now comes from four separate sources: cloud services, model training, inference and AI agents, and physical AI. Each, it said, could offset weakness in the others. The company is also trying to move hard drives into faster AI workloads that are currently served by flash memory.
