Seagate HAMRs Out Production Deal For 44TB Mozaic4+ Drives With Hyperscaler
Bitdefender, Wednesday, March 4th, 2026
Seagate's HAMR-based Mozaic 4+ drives have been qualified and put into production at least one leading hyperscaler, the storage vendor has revealed.
Seagate said the qualification supports capacities up to 44TB, and reflects production-scale deployment in hyperscale environments. Further customer qualifications are underway, Seagate said.
In fact, while the company's initial statement said it was in production at one hyperscale, in a briefing call, the vendor's CEO, Dave Mosley, said two hyperscalers were in production with the technology.
The vendor said its roadmap for the ten platter parts will scale from today's 4TB plus per disk to 10TB per disk, leading to 100TB units. This would allow customers to boost capacity without 'disruptive architectural shifts.'
