AI Boom Revives Demand for Hard Drives as HDD Component Makers Expand Capacity

Makers of hard disk drive (HDD) components are expanding production capacity in response to steady demand from servers and data centers. According to a July 2026 report from 3DNews, the AI boom has revived interest in classic storage drives, which until recently were considered a fading niche.

Why AI Revived Hard Drives

HDD demand is being driven by the server segment, where the volume of stored data is growing faster than solid-state drives are getting cheaper. Training and running AI models generates huge amounts of data — training sets, logs, checkpoints, intermediate results — that must be stored cheaply and at scale. Here, 3.5-inch HDDs with capacities in the tens of terabytes keep their key advantage over SSDs: price per terabyte. 3DNews notes that even before the AI frenzy, it looked as if classic drives were turning into a niche product and gradually giving way to solid-state storage, but the server market has changed that picture.

What HDD Makers Are Doing

Makers of HDD components have decided to expand capacity, a direct response to higher orders from data centers. This concerns not the assemblers of finished drives but the suppliers of components, on whom the volume of drive output depends. The decision to expand production is itself a signal that demand is seen not as a short-term spike but as a lasting trend that justifies investment in equipment and production lines.

"HDD component makers consider it advisable to start expanding

capacity," 3DNews says in its report.

Why This Matters for the Storage Market

In data centers, HDDs and SSDs are no longer either-or competitors; they split the roles between them. Solid-state drives take on hot data and fast access, while hard drives handle bulk, cheap storage of "warm" and "cold" information that is accessed less often. AI workloads generate both types of data at once, so demand is growing for both categories. For HDD makers, this means it is too early to write off the segment: according to 3DNews, AI infrastructure has given hard drives a second wind.

What This Means

The AI boom is reshaping not only the market for GPUs and chips but also the "boring" storage segment. Hard drives, which were already being written off as an outdated technology, have found a new source of demand in servers and data centers, and component makers judge that demand reliable enough to invest in expanding output.
