Western Digital Corporation (WDC) is a data storage company that sells hard drives, flash drives, and storage tools. Now, the company is adding a new layer to its AI story: quantum-safe security.

The drives are designed for AI data systems, where large datasets may need to remain secure for many years.
The company said the new drives are already being tested by several hyperscale customers. This is important because cloud giants and large AI firms are under greater pressure to protect long-term data, not just store more of it.
Meanwhile, WDC shares dropped 4.84% on Monday, closing at $458,68. However, despite the stock dropping in pre-market as well, Western Digital’s stock is up nearly 170% year-to-date.
Why This Matters for AI Storage
AI systems create and keep vast amounts of data. Some of that data may stay useful for years, which makes it a target for hackers who may steal encrypted data today and try to decode it later when stronger quantum computers exist.
Western Digital called this a “harvest now, decrypt later” risk. The company said its new drives are built to help defend against that threat, as well as attacks on drive firmware. In simple terms, Western Digital wants to make sure that the software running inside its drives can be trusted over time.
The new drives use ML-DSA-87 code signing, along with RSA-3072 dual signing and quantum-ready key tools. While that may sound complex, the point is simple: Western Digital is trying to build trust into the storage layer before quantum risk becomes a real day-to-day issue.
“As AI data compounds and becomes more valuable and long-lived, securing it for the future is no longer optional,” said Dr. Xiaodong Che, Western Digital’s Chief Technology Officer. He added that quantum computing is “advancing faster than many organizations anticipate.”
The Investor Takeaway
For investors, this is not likely to be a near-term earnings driver. However, it could help Western Digital stand out as AI data centers become more complex and security needs rise. The key point is that AI infrastructure is also about Storage, since AI firms need to keep large data pools safe for long periods.
As a result, Western Digital is trying to position itself as more than a seller of high-capacity drives. It wants to be seen as a key supplier for trusted AI data systems. If quantum-safe storage becomes a standard demand from cloud and AI customers, this early move could support Western Digital’s long-term role in the AI supply chain.
Is WDC a Good Stock to Buy?
Turning to the Street, Western Digital Corporation has a Strong Buy consensus, based on 15 analysts’ ratings. The average WDC stock price target is $504.33, which implies a 9.95% upside from the current price.
