After nearly two years of relative stability, the hard disk drive market is facing renewed pressure.
A report from Digitimes Asia, citing Nikkei, shows that HDD contract prices rose by about 4% quarter over quarter in the fourth quarter of 2025. This was the largest increase in eight quarters, and suppliers expect pricing pressure to continue.
The report points to two main demand drivers behind the price increase. The first comes from China’s PC market, where demand for hard drives has rebounded due to changes in government procurement policy. These policies favor PCs built with domestically produced processors and operating systems, which has accelerated local PC manufacturing.
As production increased, HDD usage also rose. Sources cited in the report said concerns over long-term data retention in solid-state drives played a role. SSDs rely on NAND flash memory, which can experience data degradation, often referred to as bit rot, over long periods of storage. As a result, some buyers have shifted back to HDDs for specific use cases, reversing what had appeared to be a steady move toward all-flash storage.
The second major source of demand comes from US data centers. Demand for high-capacity nearline HDDs continues to grow as hyperscale operators rely on them for bulk storage, backups, and cold or warm data tiers. While flash storage has expanded, spinning disks remain central to large-scale storage due to their lower cost per gigabyte.
As artificial intelligence workloads grow, so does the amount of data generated and stored. Much of that data ends up on large-capacity hard drives, adding further strain to supply.
TrendForce data referenced in the report indicates that HDD manufacturers are already operating at full capacity but still cannot keep up with demand from cloud service providers. Nearline HDD prices also rose by around 4% quarter over quarter, suggesting the issue extends beyond the PC market.
The renewed pressure on HDD pricing is closely tied to the broader expansion of AI infrastructure. Data centers are consuming not only GPUs and accelerators, but also memory, storage, power equipment, and construction resources. High-bandwidth memory and enterprise DRAM are already in short supply, and higher DRAM prices have increased manufacturing costs for hard drive makers, which rely on DRAM for cache memory.
This surge in AI-related investment has become visible at a macroeconomic level. Analysts have noted that a large share of recent US GDP growth has come from capital spending tied to data centers, servers, and related infrastructure rather than consumer demand. HDDs form part of that same investment cycle.
Unlike flash memory, which can scale through new fabrication plants and process improvements, HDD production depends on specialized components such as read and write heads and precision media. Expanding capacity is slow and costly, and manufacturers have been cautious after years of consolidation and pricing pressure. As a result, the market can tighten quickly when demand rises from multiple sources at the same time.
The broader takeaway is that hard drives, often viewed as a mature technology, are once again becoming central to the industry’s growth story. Shifting procurement policies in China and sustained demand from AI data centers have reshaped expectations for the HDD market. Whether the current pricing pressure becomes a longer cycle or eases will depend on how quickly supply can expand and whether AI infrastructure spending continues at its current pace.
