High-capacity HDD roadmap: the race to 100TB and zettabyte-scale storage — Toshiba, Seagate and WD outline three distinct strategies

Seagate, Toshiba, and Western Digital are revising HDD roadmaps as data-center and AI storage demand keeps climbing.

Seagate is pushing hardest with HAMR, while Toshiba and Western Digital are taking more conservative paths such as FC-MAMR, ePMR, ePMR2, and SMR.

All three manufacturers are targeting much larger nearline drives, with 100TB-class capacity now part of the long-term roadmap.

The article highlights that HDDs remain strategically important for zettabyte-scale storage needs because they still offer strong cost-per-terabyte advantages.
