History of Western Digital
- Founded: 1970
- Founders: Alvin B. Phillips
Alvin B. Phillips founded the company in Newport Beach, California, in 1970 as General Digital Corporation, making semiconductor test equipment. It took the Western Digital name in 1971 and spent the decade producing calculator chips, floppy disk controllers, and the MCP-1600 microprocessor.
The 1988 acquisition of Tandon's disk drive business moved it into hard drive manufacturing, where it survived the industry consolidation that eliminated most competitors through the 1990s. Its color-coded drive lines, Blue for mainstream, Black for performance, Red for NAS, became the retail identity of PC storage.
In 2012 the company bought Hitachi Global Storage Technologies for about $4.8 billion, gaining enterprise-class drive technology and the Ultrastar line. A 2016 bet on SanDisk for roughly $19 billion added flash memory, but the combined model underperformed and activist investor Elliott Management pushed for a breakup.
The Flash separation completed February 21, 2025, and the rebranding to WD followed on February 1, 2026. The brand now stands for hard drives only, riding record demand from AI data centers that need cheap mass storage. Fiscal 2026 revenue hit $12.92 billion, up 36%.

Western Digital Recalls & Controversies
The brand's issues are industry-standard rather than defining: periodic patent litigation with Seagate and others, and occasional class actions over drive marketing or warranty terms, none material.
Its operational risk is geographic. The 2011 Thailand floods crippled WD's manufacturing and showed the concentration risk of making most drives in one region. The company has since diversified sites but still depends heavily on Thai and Malaysian plants.
