HDD price squeeze 2026: WD and Seagate sold out, lead times top a year

Reported by HDDHunt on 2026-10-10. Summarized and analyzed by XAIPART Editorial.

What happened

The hard drive market has consolidated into what HDDHunt describes as a de facto duopoly: Western Digital and Seagate are essentially the only volume HDD manufacturers left, with Toshiba producing at much smaller scale. When AI-scale demand hit that structure in 2026, both suppliers ran out of sellable inventory.^S1

On its most recent earnings call, Western Digital's CEO told investors the company is "pretty much sold out for calendar '26," holding firm purchase orders from its top seven customers plus long-term agreements with two of them covering 2027 and one covering 2028.^S1 Seagate is similarly allocated: CEO Dave Mosley said nearline capacity is fully committed through 2026, with the company only now preparing to accept orders for the first half of 2027. Reporting around both calls puts Seagate's ability to fill near-term demand at roughly half to two-thirds.^S1 Enterprise lead times on the largest drives have stretched from a few weeks to more than a year, and prices have consolidated at elevated levels rather than easing.^S1

The memory market compounds this. NAND flash prices have roughly doubled in six months as wafer capacity shifts toward high-bandwidth memory for AI accelerators, and TrendForce's late-September 2026 forecast projects a further 15-20% quarter-over-quarter rise in NAND contract prices in Q4 2026, with DRAM up 10-15%.^S1 Scarce high-capacity SSDs push buyers back toward spinning disks, while onboard DRAM caches and controller silicon raise HDD build costs independently of demand.^S1
