Western Digital, founded in 1970 as General Digital Corporation and reincorporated under its current name in 1971, is a global manufacturer of data storage solutions. The company began as a semiconductor test equipment and calculator chip maker before pivoting to floppy disk controller design in the 1980s and subsequently to the magnetic recording and NAND flash technologies that define its business today. It has accumulated over 50 years of engineering expertise across hard disk drives (HDDs) and solid-state storage (SSDs).
The company designs and delivers storage products across a broad spectrum of use cases - from personal and creative workflows to large-scale enterprise data centres and AI-driven infrastructure. Its portfolio is organised around several distinct brands: WD for mainstream consumer and professional storage, SanDisk for flash-based storage products, WD_BLACK targeting gamers and performance-focused users, and G-Technology for high-performance external storage aimed at creative professionals.
Western Digital operates globally and has positioned itself at the intersection of data infrastructure and artificial intelligence, supplying storage technology that underpins data capture, preservation, and access at scale. Its technical domains span semiconductor design, magnetic recording, NAND flash engineering, HDD and SSD development, and storage systems for AI workloads.
