The company markets and sells its products globally and describes its manufacturing footprint as global. Its stated mission is to lead the data-storage market by delivering solutions for today and the future, with a vision to “unleash the power and value of data.” [5][6][7] For the fiscal year ended July 3, 2026, Western Digital reported net revenue of $12.919 billion.[8] [1][2][3][4][5][6][7][8]
Products & services
Western Digital’s current portfolio is centered on hard disk drives (HDDs), with products serving cloud and enterprise storage, client devices, and consumer storage. Its cloud and enterprise drives are designed for hyperscale and private-cloud data centers, enterprise systems, and smart-video applications; client HDDs target desktop and notebook OEMs, while consumer products include branded external storage. Cloud accounted for 89% of FY2026 net revenue.[9][10][4][11]
Named products include the Ultrastar DC HC690, a 32TB data-center HDD available with SAS or SATA interfaces and using an 11-disk SMR platform with UltraSMR and energy-assisted PMR. WD’s technology roadmap also includes ePMR, OptiNAND, UltraSMR, HAMR, and triple-stage actuators to increase capacity and areal density and reduce cost per terabyte. WD reported initial shipments of drives with up to 40TB capacity using ePMR in FY2026 Q4; HAMR is part of its next-generation roadmap.[12][13][14][15]
Consumer and client offerings include My Passport portable and My Book desktop external HDDs, alongside WD Blue desktop, WD Red Plus NAS, WD Purple surveillance, and WD_BLACK gaming drives. The cited My Passport USB-C model offers up to 6TB capacity and transfer speeds up to 5Gb/s; the My Book listing includes backup software and password protection. The company’s disclosures describe products and related software rather than a material standalone services business.[5][16][17][18] [9][10][4][11][12][13][5][14][15][16][17][18]

Company history
Western Digital was founded by Alvin B. Phillips as General Digital Corporation on April 23, 1970, initially making MOS test equipment and semiconductor products. It adopted the Western Digital name in 1971 and later shifted toward storage, producing hard drives after acquiring Tandon’s disk-drive business in 1988.[28][29]
The company expanded its storage business through the acquisition of Read-Rite assets in 2003 and Hitachi Global Storage Technologies in 2012.[30][31] In 2016, it completed the acquisition of SanDisk, broadening its business into flash storage; in 2025, Western Digital separated its Flash business through the distribution of Sandisk shares.[32][33] [28][29][30][31][32][33]
