Toshiba, Seagate, and Western Digital outlined divergent strategies for next-gen hard drives targeting 100TB+ capacities. Toshiba pursues heat-assisted magnetic recording (HAMR); Seagate focuses on energy-assisted approaches; WD backs perpendicular recording advances—each betting on different materials science to beat zettabyte-scale storage demand.
Cloud hyperscalers and tier-2 data centers face rising per-exabyte costs. The race to 100TB aims to cut TCO per stored gigabyte and reduce power per unit capacity—critical for large-scale training datasets and archival workloads supporting AI infrastructure over 2026–2028.
