Seagate Qualifies 40+TB HAMR HDDs At Two Leading Data Center Companies
Summary
Seagate has begun shipping its 4+TB HAMR HDDs, designed to meet the increasing demands of AI data center workloads. These drives have already been qualified by two major hyperscale data center companies, marking a significant advancement in storage technology.
Key Insights
What is HAMR technology?
HAMR (Heat-Assisted Magnetic Recording) is a storage technology that uses a tiny laser on the recording head to briefly heat a small spot on the disk platter to over 400°C, temporarily lowering the magnetic coercivity of high-stability materials like iron-platinum alloy (FePt). This allows denser data bits to be written reliably, enabling areal densities beyond 3TB per disk while maintaining thermal and magnetic stability, as the heated spot cools in nanoseconds without affecting overall drive temperature.
What do 'qualified' and 'hyperscale data center companies' mean in this context?
'Qualified' means the 40+TB HAMR HDDs have undergone rigorous testing and validation by two leading hyperscale data center companies (large-scale operators like those running massive cloud infrastructure), confirming reliability, performance, and compatibility for deployment in AI workloads. Hyperscale refers to data centers with thousands of servers, driving demand for high-capacity storage like these drives.
