Seagate introduces 30TB Exos M and IronWolf Pro hard drives using HAMR technology, aiming to meet growing storage demands in AI and data centers.

Seagate's Breakthrough in Storage Technology

Seagate, a leading hard drive manufacturer, has officially launched its highly anticipated 30TB hard disk drives (HDDs) based on Heat-Assisted Magnetic Recording (HAMR) technology. The new Exos M and IronWolf Pro models, built on Seagate's Mosaic 3+ platform, are now available globally through the company's online store and authorized resellers

HAMR Technology: Pushing the Boundaries of Storage Density

HAMR technology, which Seagate has been developing for over two decades, employs tiny lasers to heat and expand parts of the drive platter momentarily. This process allows for writing data at higher densities than conventional methods. The Mosaic 3+ platform incorporates a specialized plasmonic writer subsystem with a vertically integrated nanophotonic laser, heating a small spot on the FePt recording layer to approximately 450°C (842°F)

Technical Specifications and Performance

The new 30TB HDDs operate at 7,200 RPM and feature a 512 MB multi-segmented cache. They offer a maximum sustained transfer rate of 275 MB/s, slightly higher than previous-generation drives. Random performance is rated at up to 170/350 random read/write IOPS (4K, QD16)

AI and Edge Computing Driving Demand

Seagate emphasizes that the surge in AI infrastructure investment is expected to dramatically increase demand for high-capacity storage solutions. Trends like data gravity and the rise of hybrid cloud are shifting network focus toward edge computing, with nearly 150 countries moving toward implementing local data residency requirements

Competition in the High-Capacity HDD Market

While Seagate leads with commercially available HAMR-based drives, competitors are not far behind. Western Digital has announced plans for HAMR-based drives in 2027, while Toshiba is testing HAMR drives with potential sampling in 2025
