Western Digital Corporation develops, manufactures, and sells data storage devices and solutions based on hard disk drive technology worldwide, including in the United States, Asia, Europe, the Middle East, and Africa. Founded in 1970 and headquartered in San Jose, California, the company offers a comprehensive portfolio of hard disk drives segmented by use case, such as WD Blue for general computing; WD Purple and Purple Pro for surveillance systems; WD Red, Red Plus, and Red Pro for small office/home office, network-attached storage, and high-performance NAS; WD Black for gaming and high-performance applications; WD Gold for enterprise environments; and Ultrastar for data centers, along with external drives under brands including My Passport, My Book, WD Elements, and Easystore; data center platforms; network-attached storage systems; and related accessories.
