Seagate says it is preparing to begin qualification of 50TB-class hard drives in late 2027, extending the capacity roadmap of its heat-assisted magnetic recording platform. At the same time, the company indicates that much of its production capacity is already committed through 2028. The 50TB products will primarily target hyperscale and enterprise customers rather than conventional desktop PCs. HAMR technology increases areal density by briefly heating a microscopic section of the disk surface immediately before data is written. Training datasets, model checkpoints, user data, logs, and generated content require large storage tiers, including both fast flash and economical nearline hard drives.
