Seagate reaches 34TB capacity using SMR technology for high-density storage
Thursday, April 2, 2026 at 12:08 AM
Seagate has reportedly advanced its storage capacity using Shingled Magnetic Recording (SMR) technology to reach 34TB. This highlights the company's progress in high-capacity hard disk drive manufacturing for data center infrastructure.
Context
Seagate has reached a new milestone in high-density storage by utilizing Shingled Magnetic Recording (SMR) technology to achieve 34TB capacities. This development follows the company's recent aggressive scaling of its Mozaic 3+ and Mozaic 4+ platforms, which utilize Heat-Assisted Magnetic Recording (HAMR) to push areal densities beyond traditional limits. By early 2026, Seagate successfully moved its Mozaic 4+ platform into production, supporting capacities up to 44TB for hyperscale cloud providers. These advancements are critical as AI-driven data creation is forecast to reach 527ZB by 2029, tripling the demand for data center storage capacity. Compared to older perpendicular recording, Seagate’s latest HAMR-based drives offer a 45% improvement in power consumption per terabyte and a 25% reduction in total cost of ownership, providing the massive scale required for modern AI training and archival workloads.
