Mozaic HAMR platform
Mozaic 4+ drives up to 44TB are shipping in volume to two hyperscale cloud providers, with more customer qualifications under way.
The numbers
What it is
Seagate's heat-assisted magnetic recording (HAMR) platform for high-capacity hard drives. Mozaic 4+ drives reached volume shipments to two cloud customers in March 2026, and Seagate says broader availability is planned as production scales.
Why it matters to the stock. HAMR lets Seagate ship more terabytes per drive. Faster qualification with more cloud customers is the main test of whether the company can keep its data center pricing and margins.
