Hard Disk Shipments Decline While Capacity Rises
In early May 2025, analyst Thomas Coughlin and industry sources reported that annual HDD unit shipments have fallen from roughly 600 million in 2010 to about 150 million in 2025, with hyperscale datacenter operators purchasing the majority. Despite lower unit counts, shipped HDD capacity is rising as vendors focus on high-capacity nearline drives for AI and cold data; enterprises shift primary workloads toward SSDs and NVMe HDDs are being prototyped.
Key Points
- 1Report shows HDD unit shipments fell from ~600M (2010) to ~150M (2025).
- 2Hyperscale datacenters now buy most HDDs, driving tailored high-capacity nearline product development.
- 3Adopt HDDs for cold AI datasets while using SSDs for primary, performance-critical storage.
Scoring Rationale
Industry-level market shift with credible analyst and vendor sources, but incremental rather than transformative technological change.
