What is a hard disk drive (HDD)?

Hard disk drives (HDDs) have been proven and trusted for decades. They are the cornerstone of data centers, enterprises, and creative studios worldwide. This technology, using rotating platters and read/write heads, has been continuously improved over decades to achieve reliability, massive capacity, and long-term data storage. Modern HDDs, such as the Western Digital Ultrastar series, with single-pane capacities up to 32TB, are the foundation of hyperscale data centers and enterprise storage infrastructure. With technologies such as energy-assisted perpendicular magnetic recording (ePMR) and heat-assisted magnetic recording (HAMR), HDD capacity continues to increase while maintaining cost advantages.
