Western Digital Corporation

Western Digital Corporation, operating under the brand name WD, is an American data storage company headquartered in San Jose, California. Established in 1970, the company is a global leader in designing, manufacturing, and selling data storage devices and solutions. Its mission is to innovate and drive the future of data, empowering users to capture, preserve, access, and protect their digital content.

The company offers a broad portfolio of products, including high-capacity hard disk drives (HDDs) for enterprise and consumer use, as well as NAND flash-based solid-state drives (SSDs) and flash memory cards. These solutions cater to diverse market segments such as enterprise data centers, cloud computing, personal computing, gaming, and mobile devices, with key customer segments being Cloud, Client, and Consumer. Its brands include WD and SanDisk Professional.

In a significant strategic move, Western Digital completed the separation of its Flash business unit into the independent SanDisk Corporation on February 21, 2025, with Western Digital now primarily focused on hard disk drives. The company rebranded to "WD" in February 2026, reflecting its role as essential infrastructure for the AI-driven data economy. Led by CEO Irving Tan, Western Digital reported strong financial results for Q3 fiscal 2026, with revenue increasing 45% year-over-year, driven by robust demand in the cloud sector and for high-capacity storage solutions supporting artificial intelligence.
