About Western Digital
Western Digital is a data storage company. It makes enterprise hard drives and solid state drives, selling them to cloud providers, data centers, and device makers who need somewhere to keep the world's data.
Its AI-focused portfolio includes Ultrastar data center SSDs, an AI-optimized hard drive platform, OpenFlex storage systems, and reference data center architectures for AI. Training AI models requires holding enormous datasets, and much of that sits on high-capacity drives like Western Digital's.
Founded in 1970 and headquartered in San Jose, California, Western Digital trades on the NASDAQ, employs roughly 51,000 people, and is led by CEO Tiang Yew Tan.
Western Digital in the AI buildout
Western Digital sits in the Memory & Storage layer of the AI buildout. AI training runs on massed data, and cloud and AI data centers buy its high-capacity drives as the cheap bulk storage tier underneath that data. AI-driven nearline demand underpins the growth story, though the company also rides general cloud and client storage cycles that have nothing to do with AI. Supercycle scores Western Digital's AI exposure at 42 out of 100.
WDC is tracked in Memory & Storage, rated Growing on the AI Exposure leaderboard.
