Artificial intelligence (AI) continues to dominate headlines, particularly in its influence on the S&P 500. Nvidia has long been the leading name in this sector, with its graphics processing units (GPUs) functioning as essential tools for machine learning, cloud computing, and generative AI. However, as 2025 unfolds, Nvidia’s performance raises questions, especially as it lags behind competitors like AMD, Broadcom, and Super Micro Computer, leading some investors to reconsider its seemingly inflated valuation.
As investment shifts away from overhyped semiconductor companies, the focus is turning towards a crucial aspect of AI infrastructure: digital storage. Each AI query necessitates storage, and as the number of these queries multiplies, the demand for efficient data storage solutions grows immensely. External solid-state drives (eSSD), known for their reliability and efficiency over traditional hard disk drives (HDDs), are witnessing increased adoption.
The proliferation of generative AI is noteworthy, surging from 33% usage in 2023 to an astonishing 65% in 2024. As these AI models expand, so does the need for storage, drawing parallels to the gold rush in Coloma during the 1850s—while many prospectors may have faltered, the sellers of shovels prospered. In today’s market, companies that provide digital storage are akin to those shovel sellers of the past. Among the notable players in this field are Seagate Technology and Western Digital.
Seagate’s stock has skyrocketed by 120% in 2025, although it may now appear somewhat overvalued. In light of this, Western Digital has become a focal point of interest. As a major producer of HDDs, SSDs, and flash memory, Western Digital has also seen its stock surge, climbing 109% this year. Recent quarterly performance highlights this upward trajectory, with revenues hitting $2.61 billion—a remarkable 30% year-on-year increase that exceeded analyst expectations by nearly 5%.
The company’s cloud business has been a significant driver of growth, now comprising 90% of total sales, and witnessing a 36% increase. Demand for next-generation storage solutions is robust, as evident in the doubling of shipments for its 26TB CMR drives and 32TB UltraSMR drives. Such innovation aligns perfectly with the burgeoning data requirements of AI developers.
Financially, Western Digital maintains a stronger posture compared to some competitors. While Seagate’s liabilities exceed its assets, Western Digital boasts a balanced balance sheet with a debt-to-equity ratio of 0.96. Its operating cash flow recently reached $1.87 billion, providing a solid foundation for investment in the next phase of storage technologies.
Analysts are optimistic regarding Western Digital’s prospects. On September 8, Citigroup reaffirmed a Buy rating and raised its price target from $88 to $110. Predictions suggest that earnings may grow by 31.9% in the financial year ending June 2026, and its forward price-to-earnings ratio of 14.4 appears reasonable, especially when compared to many AI-related stocks sporting steep valuations.
However, risks loom on the horizon. Western Digital faces intense competition from Seagate, Micron, and Samsung, all vying for the same enterprise storage contracts. A significant portion of its revenue is dependent on a limited number of large customers; should one decide to reduce orders or switch vendors, the consequences could be severe. Additionally, like Nvidia, there is always the potential for inflated valuations driven by market enthusiasm.
Despite these risks, Western Digital’s valuation appears more pragmatic than many of its AI counterparts. With robust revenue growth, improving profit margins, and a solid financial position, it presents a compelling option for investors seeking a more stable entry into the AI boom.
