AI data centers have bought out hard drive supply through 2028 — and you'll pay for it
Hard drive and SSD prices have jumped roughly 50% since late 2025, and the cause is straightforward: Western Digital and Seagate have pre-sold the vast majority of their production capacity to AI data centers under contracts stretching to 2028 and 2029. If you've tried to buy a high-capacity hard drive recently and found empty shelves or eye-watering prices, this is why.
How the contracts work
The storage industry has quietly abandoned spot-market trading — where prices fluctuate daily based on supply and demand — in favor of build-to-order agreements with the world's largest cloud companies. Western Digital CFO Luis Visoso confirmed the company is now signing five-year SSD supply contracts that lock in quarterly volumes and blended pricing years in advance. WD CEO Irving Tan added that contract terms with top customers now extend into 2028 and 2029, per Tom's Hardware.
Seagate's situation is similar. CEO William Mosley said nearline HDD capacity — drives used in data centers for regularly accessed but not always-on storage — is nearly fully allocated through the end of 2027, with strategic discussions for 2028 already underway. Every exabyte is manufactured to a specific customer order before it leaves the factory.
What this means at retail
WD's Q2 2026 earnings showed 89% of revenue now coming from cloud and hyperscale customers, versus just 5% from consumers. Retail has become an afterthought. The knock-on effect is severe: NAND Flash wafer spot prices have risen 757% against their mid-2025 baseline, according to Gamers Nexus. Consumer hard drive prices at major US and UK retailers have surged around 50% in the four months between December 2025 and April 2026, with many popular models listed as indefinitely out of stock.
Competitors Crucial and Kingston have flagged 2026 as a "production constrained" year, meaning no relief is coming from the second tier either. Analysts see no meaningful easing before 2028 at the earliest.
The longer view
AI inference workloads and the explosive growth of data lakes — vast repositories of raw data that AI models train on and query — are driving structural, not cyclical, demand for storage. This isn't a temporary shortage like the GPU crunch of 2021; manufacturers are building permanent supply pipelines for hyperscalers at the direct expense of the consumer market.
For anyone buying a NAS, upgrading a gaming PC, or expanding a small business server, the advice is blunt: buy what you can find now at current prices, because the trajectory through 2027 points only upward.
