The stock market is witnessing a significant rally in hard drive and storage companies, driven by remarks from Nvidia CEO Jensen Huang regarding the critical role of memory storage in artificial intelligence (AI). During the Consumer Electronics Show (CES) 2026, Huang highlighted the memory storage market as a “completely unserved” sector, which has led to a surge in stock prices for key players in the industry.
SanDisk, a flash-memory company that was spun out of Western Digital last year, has emerged as a standout performer. On Tuesday, its shares soared approximately 28%, marking the most robust intraday performance since February. This surge has propelled SanDisk’s stock price upward by over 40% in the early days of January, making it the top performer in the S&P 500 for that day.
Other major companies in the hard drive sector are also experiencing notable gains. Western Digital saw its shares increase by around 17%, while Seagate Technology recorded a rise of about 14% on the same day.
Huang emphasized the growing necessity for data storage, stating, “This market will likely be the largest storage market in the world, basically holding the working memory of the world’s AIs.” He pointed out that the increasing demands of AI are straining the current data storage ecosystem, describing the amount of context memory processed as “way too high.”
Memory prices are reflecting this heightened demand. According to a report from Korea Economic Daily, Samsung Electronics and SK Hynix are advocating for server DRAM price increases of between 60% and 70% in the first quarter compared to the previous quarter. Market analysis firm Counterpoint forecasts that memory prices could rise by 40% through the second quarter of 2026, further indicating that AI-driven demand is putting pressure on supply.
The importance of data storage has gained prominence in discussions surrounding the AI landscape. While the focus has traditionally been on semiconductors, data centers, and power requirements, it is clear that data storage is emerging as a crucial bottleneck. Analysts predict that the volume of stored global data could exceed 200 zettabytes by 2025, equivalent to 200 billion terabytes.
In a note from December, an analyst from the International Data Corporation stated, “The memory market is at an unprecedented inflection point, with demand materially outpacing supply.” This shift is attributed to the rapid expansion of AI infrastructure and workloads, marking a departure from the memory market’s historical boom-and-bust cycles.
For both consumers and enterprises, this marks the end of an era characterized by cheap and abundant memory and storage, at least in the medium term. As the industry adapts to these evolving demands, the implications for pricing and availability are significant, reshaping the landscape of data storage in an AI-driven world.
