Seagate's 3TB/platter HAMR Drives: A Game Changer for AI Data Storage
2025-07-16
Seagate has unveiled new hard drives based on its Mosaic 3+ platform, utilizing its unique HAMR technology to achieve areal densities of 3TB per platter and beyond. The press release heavily emphasizes the drives' suitability for AI data storage, though their massive capacity makes them ideal for any application requiring immense storage in a small footprint. While consumer PCs have largely shifted to SSDs, HDDs remain cost-effective for massive data centers where ultra-high speeds aren't paramount. Competitor Western Digital anticipates HAMR drives in 2027, while Toshiba plans 2025 sample testing.
