Hyperscalers Drive 2026 Hard‑Drive Sellout as Western Digital and Seagate Lock In Capacity

Hyperscalers are locking in high‑capacity nearline models through long‑term deals.

Overview

  • Western Digital’s CEO Irving Tan said the company is “pretty much sold out” for calendar 2026 and has long‑term agreements with two customers for 2027 and one for 2028.
  • Seagate’s Dave Mosley reported nearline capacity is fully allocated through 2026 and said the company expects to start taking orders for the first half of 2027 in the coming months.
  • The squeeze is driven by AI data centers and cloud providers concentrating demand on high‑density 18TB–22TB hard drives used for large‑scale storage.
  • Analysts say little open production remains for discretionary buyers, pressuring mid‑size enterprises and standard server refresh plans as prices rise and channel availability tightens.
  • Some organizations are delaying projects or pivoting to SSDs despite higher costs, and any manufacturing adjustments will take time to relieve the shortage.
