Toshiba Successfully Demonstrates Nearline HDDs with Massive Capacity of Over 30 Terabytes

5 months ago

Toshiba Electronics Europe GmbH has announced Toshiba Electronic Devices & Storage Corporation’s successful demonstration of over 30TB storage capacities using next-gen HAMR and MAMR technologies for HDDs, advancing towards commercialization.

HAMR boosts writing capabilities by locally heating the disk material with a near-field laser. Toshiba achieved 32TB on 10 disks using Shingled Magnetic Recording (SMR) – a technology that partially overlaps data tracks to increase the areal density and overall storage capacity per disk. Toshiba plans to start shipping test sample HDDs of 28 – 30TB with HAMR technology in 2025.

The other technology is MAMR, which uses microwaves to enhance magnetic recording capabilities. Toshiba was the first to demonstrate its effectiveness and started mass production of first-generation drives in 2021. Toshiba achieved 31TB capacity by stacking 11 disks, using SMR technology, and improving signal processing.

These new achievements were made possible through years of close collaboration with Resonac Corporation, an HDD media manufacturer, and TDK Corporation, an HDD head manufacturer. Toshiba and its working partners are committed to continuing to develop HAMR and MAMR technologies to provide higher-capacity HDDs to meet the growing storage demand of the cloud and data centers.

As Larry Martinez-Palomo, Vice President, Head of Storage Products Division at Toshiba, said, “Toshiba is concurrently advancing the development of future generation high- capacity HDDs using both HAMR and MAMR technologies. Mass production of hard disk drives incorporating HAMR will commence after the validation phase is completed. In the interim, Toshiba will continue to satisfy the demand for high-capacity, high-reliability storage devices with hard disk drives employing the field-proven MAMR technology.”
