Western Digital is a global data storage company founded in 1970 as General Digital Corporation by Alvin B. Phillips, and reincorporated under its current name the following year. Originally focused on semiconductor test equipment and calculator chip manufacturing, the company shifted over subsequent decades into magnetic storage - producing floppy disk controllers in the 1980s before establishing itself as a major force in hard disk drives and, later, solid-state storage. Today it draws on over 50 years of expertise in magnetic recording and NAND flash technology.
The company designs and manufactures storage solutions that span personal creative workflows through to large-scale enterprise data centers, including infrastructure built for AI workloads. Its product portfolio is organised around several brands:
- WD - storage solutions for personal and professional use cases
- SanDisk - flash-based storage products
- WD_BLACK - high-performance storage
- G-Technology - storage solutions with a professional focus
Western Digital operates globally, with its technologies present across consumer devices and enterprise data centers alike. The company's technical domains include hard disk drives (HDD), solid-state drives (SSD), and data storage infrastructure, with an increasing emphasis on the storage requirements of AI-driven computing environments.
