Seagate stock gets Azure validation for HAMR-SMR storage

Seagate announced on October 26, 2026, that Microsoft Azure Storage had completed qualification of a Broadcom host bus adapter with Seagate HAMR and SMR technology. The company presented the milestone as a way to simplify high-capacity storage deployment for AI and cloud infrastructure. The announcement is detailed in the Seagate press release.

Hyperscale validation strengthens the roadmap

Seagate said its Mozaic drives, based on heat-assisted magnetic recording, or HAMR, and configured with shingled magnetic recording, or SMR, are the first and only SMR drives on Broadcom's approved vendor list for the host bus adapter. The adapter connects servers with storage systems and helps data centers manage large hard-drive fleets.

Microsoft Azure's qualification provides a hyperscale proof point for the configuration, but it does not disclose a deployment schedule or expected drive volume. The commercial relevance lies in easier integration of high-capacity drives as AI workloads increase storage requirements.

Execution remains the next share test

Seagate's fiscal second-quarter outlook still depends on stronger shipments, customer qualifications and manufacturing execution. Management expects revenue of 4.8 billion US dollars, plus or minus 100 million US dollars, and non-GAAP diluted earnings of 9.20 US dollars per share, plus or minus 0.20 US dollars. HAMR is expected to represent roughly half of the nearline exabyte shipment run rate by the end of calendar 2026, while Mozaic 4 is ramping with two leading cloud providers.

Seagate stock traded at 442.00 euros on Lang & Schwarz at 17:42 CET on Tuesday, November 10, 2026.
