New Seagate 44TB Hard Drives Signal Next Phase Of Data Center Capacity Growth
Techstrong.IT, Monday, March 9th, 2026
Seagate's hard drives that can store up to 44 terabytes, part of its Mozaic 4+ platform, are now deployed by hyperscalers, the company announced. The platform uses heat-assisted magnetic recording (HAMR), a technology that boosts storage density beyond what conventional hard drive designs can support.
The rollout reflects the growing pressure on data centers to expand storage capacity as AI systems devour ever larger pools of data for AI training and long-term retention. Cloud vendors depend heavily on high-capacity HDD because they remain an economical way to store huge volumes of information.
'As AI models have evolved and generative applications have expanded, the demand for massive datasets, both real and synthetic, has become essential,' said Bob O'Donnell, president of research firm TECHnalysis Research. Higher-capacity drives, he said, are becoming a critical part of maintaining the performance and reliability of AI systems.
