In late July 2026 Seagate reiterated its rapid scaling to meet AI‑driven data‑center storage demand. After reporting a record Q4 profit and announcing the Mozaic 5+ platform, the company said the next‑generation HAMR‑based drives will qualify 50 TB HDDs by late 2027, with commercial‑volume shipments expected in 2028. Near‑line production capacity is already booked through 2028, pushing broader market availability to 2029. Seagate noted that 50 % of exabytes shipped with HAMR technology in 2026 will come from Mozaic 5+, and it aims to demonstrate 10 TB per platter by 2028, laying groundwork for future 100 TB drives. Fiscal‑2026 revenue rose to $3.6 billion, up 48 % YoY.

The third‑quarter report showed revenue of $3.11 billion, a non‑GAAP gross margin of 47 % and free cash flow of $953 million, with a quarterly dividend of $0.74 per share. Seagate highlighted the earlier Mozaic 4 generation, which can deliver up to 44 TB per drive—a 30 % capacity boost over the first generation—using the same disk and head count and modest material‑cost changes. The roadmap projects Mozaic 5+ to exceed 5 TB per platter, enabling ten‑platter 50‑TB drives, and targets 100‑TB drives by 2032 and larger capacities thereafter. Competitors such as Western Digital, Micron and Toshiba are pursuing similar high‑density HDD technologies.

## Claims

- Demand for cold‑storage hard drives is so strong that most production capacity is allocated through 2028. (corroborated by 5 sources)
- Most near‑line capacity for 2028 has already been allocated to AI and hyperscale customers, pushing broader availability to 2029. (corroborated by 5 sources)
- The Mozaic 5+ platform uses ten platters and HAMR technology to achieve over 50 TB per drive. (corroborated by 5 sources)
- Seagate will qualify shipments of 50 TB HDDs on the Mozaic 5+ platform in late 2027. (corroborated by 4 sources)
- Seagate will deliver 50 TB hard drives based on HAMR technology in 2027. (corroborated by 3 sources)
- By the end of 2026, 50 % of exabytes shipped with HAMR technology will be from the Mozaic 5+ platform. (corroborated by 3 sources)
- First validation samples of Mozaic 5+ drives will be sent to customers in 2027. (corroborated by 3 sources)
- Commercial volume shipments of the 50 TB HDDs are expected in 2028. (corroborated by 3 sources)
- Seagate's current Mozaic 4+ platform supports drives up to 44 TB. (corroborated by 2 sources)
- Seagate reported Q4 fiscal 2026 revenue of $3.6 billion, up 17 % quarter‑over‑quarter and 48 % year‑over‑year. (single source)
- Seagate aims to demonstrate 10 TB per platter by 2028. (single source)

## Timeline

### 2026-08-02: Seagate launches Mozaic platform, targets 50‑TB HAMR drives by 2027

Seagate posted $3.11 bn Q3 revenue and highlighted its Mozaic platform, which can deliver 44 TB disks and is slated to reach 50 TB HDDs by late 2027, underscoring a cost advantage over SSDs.

### 2026-07-30: Seagate targets 50TB HDDs for 2027 as AI demand outpaces supply

Seagate will qualify 50 TB HAMR HDDs on its Mozaic 5+ platform in late 2027, with commercial shipments in 2028, but AI‑driven demand has already booked most 2028 capacity, delaying wider availability to 2029.
