Western Digital has announced a breakthrough innovation for delivering ultra-high capacity hard disk drives to meet the future demands of Big Data with proven data center-level reliability: new microwave-assisted magnetic recording (MAMR) technology should enable hard drives with 40TB of capacity by 2025, helping HDDs hold onto their staying power in the enterprise segment.
At the heart of the company’s innovation breakthrough is the "spin torque oscillator" used to generate a microwave field that increases the ability to record data at ultra-high density without sacrificing reliability. Western Digital’s innovative MAMR technology is expected to offer over 4 terabits-per-square-inch over time. With sustained improvements in recording density, MAMR promises to enable hard drives with 40TB of capacity and beyond by 2025, and continued expansion beyond that timeframe.
