Western Digital was founded on April 23, 1970, by Alvin B. Phillips, a Motorola employee, as General Digital Corporation, initially a manufacturer of MOS test equipment.{{Cite web |url=https://www.bizjournals.com/sanfrancisco/blog/2012/10/western-digital-plans-77-layoffs-at.html |title=Western Digital completes 77 layoffs at Fremont plant |last=Dunn |first=James |date=5 October 2012 |website=San Francisco Business Times |access-date=2020-04-10}} It was originally based in Newport Beach, California,{{cite journal |last= |first= |date=May 10, 1971 |url=https://worldradiohistory.com/Archive-Electronics/70s/71/Electronics-1971-05-10.pdf#page=49 |title=General Data Corporation advertisement |journal=Electronics |page=49 |via=World Radio History}} shortly thereafter moving to Santa Ana, California, and would go on to become one of the largest technology firms headquartered in Orange County.{{cite news |last1=Chen |first1=I-Chun |title=Western Digital moves headquarters out of Los Angeles area |url=https://www.bizjournals.com/losangeles/news/2017/04/25/western-digital-moves-headquarters-out-of-la.html |work=Los Angeles Business Journal |publisher=American City Business Journals |date=April 25, 2017}} It rapidly became a specialty semiconductor maker, with start-up capital provided by several individual investors and industrial giant Emerson Electric. Around July 1971, it adopted its current name and soon introduced its first product, the WD1402A UART.

During the early 1970s, the company focused on making and selling calculator chips, and by 1975, Western Digital was the largest independent calculator chip maker in the world. The oil crisis of the mid-1970s and the bankruptcy of its biggest calculator customer, Bowmar Instrument,{{Cite news |last=Smith |first=William D. |title=Bowmar Will Ask Reorganization |newspaper=The New York Times |page=55 |date=February 11, 1975}} changed its fortunes, however, and in 1976 Western Digital declared Chapter 11 bankruptcy. After this, Emerson Electric withdrew their support of the company. Chuck Missler joined Western Digital as chairman and chief executive in June 1977, and became the largest shareholder of Western Digital.

In 1973, Western Digital established its Malaysian plant, initially to manufacture semiconductors.

Western Digital introduced several products during the late 1970s, including the MCP-1600 multi-chip, microcoded CPU. The MCP-1600 was used to implement DEC's LSI-11 system, the WD16, and their own Pascal MicroEngine microcomputer which ran the UCSD p-System Version III and UCSD Pascal. However, the WD integrated circuit that arguably drove Western's forward integration was the FD1771,{{Cite journal |last=Michalopoulos |first=Demetrios A |title=New Products: Single-chip floppy disk formatter/controller |journal=Computer |volume=9 |issue=10 |page=64 |date=October 1976 |doi=10.1109/C-M.1976.218414}}"The FD1771 is a single-chip floppy disk formatter/controller that interfaces with most available disk drives and virtually all types of computers." one of the first single-chip floppy disk drive formatter/controllers, which could replace significant amounts of TTL logic.

The FD1771 and its kin were Western Digital's first entry into the data storage industry; by the early 1980s, they were making hard disk drive controllers, and in 1983, they won the contract to provide IBM with controllers for the PC/AT. That controller, the WD1003, became the basis of the ATA interface (which Western Digital developed along with Compaq and Control Data Corporation's MPI division, now owned by Seagate Technology), starting in 1986. Throughout most of the 1980s, the family of controllers based on the WD1003 provided the bulk of Western Digital's revenues and profits, and for a time generated enormous corporate growth.

Much of the mid-to-late 1980s saw an effort by Western Digital to use the profits from their ATA storage controllers to become a general-purpose OEM hardware supplier for the PC industry. As a result, Western Digital purchased a number of hardware companies. These included graphics cards (through its Paradise Systems subsidiary, purchased 1986, which later became Western Digital Imaging), core logic chipsets (by purchasing Faraday Electronics Inc. in 1987), SCSI controller chips for disk and tape devices (by purchasing ADSI in 1986), networking (WD8003, WD8013 Ethernet and WD8003S StarLAN). They did well (especially Paradise, which produced one of the best VGA cards of the era), but storage-related chips and disk controllers were their biggest money makers. In 1986, they introduced the WD33C93 single-chip SCSI interface, which was used in the first 16-bit bus mastering SCSI host adapter, the WD7000 "FASST"; in 1987 they introduced the WD37C65, a single-chip implementation of the PC/AT's floppy disk controller circuitry, and the grandfather of modern super I/O chips; in 1988 they introduced the WD42C22 "Vanilla", the first single-chip ATA hard disk controller.

1988 also brought what would be the biggest change in Western Digital's history. That year, Western Digital bought the hard drive production assets of PC hardware maker Tandon; the first products of that union under Western Digital's own name were the "Centaur" series of ATA and XT attachment drives.{{Cite news |last=Culver |first=John. |title=History of Microprocessor Companies |url=http://www.cpushack.com/history.html#63}}

By 1991, things were starting to slow down, as the PC industry moved from ST-506 and ESDI drives to ATA and SCSI, and thus were buying fewer hard disk controller boards. That year saw the rise of Western Digital's Caviar drives, brand new designs that used the latest in embedded servo and computerized diagnostic systems.

Eventually, the successful sales of the Caviar drives resulted in Western Digital starting to sell some of its divisions. Paradise was sold to Philips, and since disappeared. Its networking and floppy drive controller divisions went to SMC Networks and its SCSI chip business went to Future Domain, which was later bought out by market leader Adaptec. Around 1995, the technological lead that the Caviar drives had enjoyed was eclipsed by newer offerings from other companies, especially Quantum Corp., and Western Digital fell into a slump.

In 1994, Western Digital began producing hard drives at its Malaysian factory, employing 13,000 people.

Products and ideas of this time did not go far. The Portfolio drive (a {{convert|3|in|mm|adj=on}} form factor model, developed with JT Storage) was a flop, as was the SDX hard disk to CD-ROM interface. Western Digital's drives started to slip further behind competing products, and quality began to suffer; system builders and PC enthusiasts who used to recommend Western Digital above all else, were going to the competition, particularly Maxtor, whose products had improved significantly by the late 1990s.

In an attempt to turn the tide in 1998, Western Digital recruited the help of IBM. This agreement gave Western Digital the rights to use certain IBM technologies, including giant magneto-resistive (GMR) heads and access to IBM production facilities. The result was the Expert line of drives, introduced in early 1999. The idea worked, and Western Digital regained respect in the press and among users, even despite a recall in 2000 (which was due to bad motor driver chips). Western Digital later broke ties with IBM.

In 2001, Western Digital became the first manufacturer to offer mainstream ATA hard disk drives with 8 MiB of disk buffer. At that time, most desktop hard disk drives had 2 MB of buffer. Western Digital labeled these 8 MB models as "Special Edition" and distinguished them with the JB code (the 2 MB models had the BB code). The first 8 MB cache drive was the 100 GB WD1000JB, followed by other models starting with 40 GB capacity. Western Digital advertised the JB models for cost-effective file servers. In October 2001, Western Digital restated its prior year results to reflect the adoption of SEC Staff Accounting Bulletin No.101 and the reclassification of Connex and SANavigator results as discontinued operations.{{cite web |url=https://www.sec.gov/Archives/edgar/data/106040/000089256901500814/a76496ex99-1.htm |title=Western Digital Reports $4 Million Profit in HDD Business on Revenue of $441 Million, Unit Shipments of 5.4 Million |date=October 25, 2001 |access-date=September 10, 2013}}

In 2003, Western Digital acquired most of the assets of bankrupt one-time market leading magnetic hard drive read-write head developer Read-Rite Corporation for $95 million.{{Cite book |title=Hoover's Handbook of American Business 2004 |publisher=Hoover's Business Press |year=2003 |isbn=1-57311-088-4 |volume=2 |location=Austin, Texas |pages=875–876 |via=Internet Archive}} In the same year, Western Digital offered the first 10,000 rpm Serial ATA HDD, the WD360GD "Raptor", with a capacity of 36 GB and an average access time of less than six milliseconds. Soon, the 74 GB WD740GD followed, which was also much quieter. In 2004, Western Digital redesigned its logo for the first time since 1997, with the design of new logo focusing on the company's initials ("WD").{{cite web |url=http://www.wdc.com/en/company/pressroom/releases/?release=f47f6109-4393-4530-b523-161587674281 |title=Western Digital Launches New Logo with Universal Appeal |date=October 6, 2004 |access-date=August 21, 2015 |archive-url=https://web.archive.org/web/20151017104113/http://www.wdc.com/en/company/pressroom/releases/?release=f47f6109-4393-4530-b523-161587674281 |archive-date=October 17, 2015 |url-status=dead |df=mdy-all}} In 2005, Western Digital released a 150 GB version, the WD1500ADFD, which was also available in a special version with a transparent window enabling the user to see the drive's heads move over the platters while the drive read and wrote data (Raptor X, WD1500AHFD). The biggest capacity 3,5 inch Raptor is the WD1600ADFD, with 160 GB of disk space. {{As of|2004}}, the Western Digital Raptor drives have a five-year warranty, making them a more attractive choice for inexpensive storage servers, where a large number of drives in constant use increases the likelihood of a drive failure.

In 2006, Western Digital introduced its My Book line of mass market external hard drives that feature a compact book-like design. On October 7, 2007, Western Digital released several editions of a single 1 TB hard drive, the largest in its My Book line.

{{Anchor|GREEN-POWER}}

In 2007, Western Digital acquired magnetic media maker Komag. Also in the same year, Western Digital adopted perpendicular recording technology in its line of notebook and desktop drives. This allowed it to produce notebook and desktop drives in the largest classes of the time. Western Digital also started to produce the energy efficient GP (Green Power) range of drives.

In 2007, Western Digital announced the WD GP drive touting rotational speed "between 7200 and 5400 rpm", which is technically correct while also being misleading; the drive spins at 5405 rpm, and the Green Power spin speed is not variable.{{cite web |url=http://www.wdc.com/wdproducts/library/SpecSheet/ENG/2879-771439.pdf#page=2 |title=WD Green Mobile Series Spec Sheet |date=June 26, 2013 |access-date=January 21, 2013 |publisher=WDC}} WD GP drives are programmed to unload the heads whenever idle for a very short period of time.{{cite web |url=http://man7.org/linux/man-pages/man8/hdparm.8.html |title=hdparm(8) - Linux manual page |date=November 2012 |access-date=March 31, 2014 |website=man7.org |quote=Get/set the Western Digital (WD) Green Drive's "idle3" timeout value.

On April 21, 2008, Western Digital announced the next generation of its 10,000 rpm SATA WD Raptor series of hard drives. The new drives, called WD VelociRaptor, featured 300 GB capacity and {{convert|2.5|in|mm|adj=on}} platters enclosed in the IcePack, a {{convert|3.5|in|mm|adj=on}} mounting frame with a built-in heat sink. Western Digital said that the new drives are 35 percent faster than the previous generation. On September 12, 2008, Western Digital shipped a 500 GB {{convert|2.5|in|mm|adj=on}} notebook hard drive which is part of their Scorpio Blue series of notebook hard drives.

On January 27, 2009, Western Digital shipped the first 2 TB internal hard disk drive.{{cite web |url=http://news.zdnet.co.uk/hardware/0,1000000091,39603775,00.htm |title=Western Digital launches 2TB hard drive |date=January 27, 2009 |access-date=January 27, 2009 |publisher=ZDNet |archive-url=https://archive.today/20120802222739/http://www.zdnet.com/western-digital-launches-2tb-hard-drive-3039603775/ |archive-date=2012-08-02}} On March 30, 2009, they entered the solid-state drive market with the acquisition of Siliconsystems, Inc. Its acquisition was unsuccessful, and few years later Western Digital discontinued all solid-state storage products based on Siliconsystems design (SiliconEdge and SiliconDrive families of SSDs and memory cards), but its inventions was used later in development of various other solid-state storage products, with larger developments going on after 2016 acquisition of SanDisk.

On July 27, 2009, Western Digital announced the first 1 TB mobile hard disk drive, which shipped as both a Passport series portable USB drive as well as a Scorpio Blue series notebook drive.{{citation needed|date=February 2023}}

In October 2009, Western Digital announced the shipment of first 3 TB internal hard disk drive, which has 750 GB-per-platter density with SATA interface.{{Cite magazine |title=WD's New 3TB Drive Packs More Storage Than 32-Bit Can Handle |url=https://www.wired.com/2010/10/western-digitals-3tb-drive-brings-more-than-32-bit-can-handle/ |magazine=WIRED |access-date=January 22, 2016 |language=en-US |date=2010-10-19}}

In March 2011, Western Digital agreed to acquire parts of the storage unit of Hitachi, HGST, for about $4.3 billion of which $3.5 billion was paid in cash and the rest with 25 million shares of Western Digital.{{cite web |url=https://www.bloomberg.com/news/2011-03-07/western-digital-to-buy-hitachi-unit-for-4-3-billion-in-cash-stock-deal.html |title=Hitachi Rises on $4.3 Billion Sale of Hard-Drive Unit to Western Digital |website=Bloomberg |publisher=Bloomberg L.P. |date=March 7, 2011 |access-date=July 17, 2013 |first1=Mariko |last1=Yasu |first2=Maki |last2=Shiraki |first3=Amy |last3=Thomson}}

In 2011, Western Digital established an R&D facility at its Malaysian plant at a cost of 1.2 billion US dollars.

In March 2012, Western Digital completed the acquisition of HGST and became the largest traditional hard drive manufacturer in the world. To address the requirements of regulatory agencies, in May 2012 Western Digital divested assets to manufacture and sell certain 3.5-inch hard drives for the desktop and consumer electronics markets to Toshiba, in exchange for one of its 2.5-inch hard drive factories in Thailand.{{cite news |last1=Ngo |first1=Dong |title=Toshiba to acquire Western Digital's 3.5-inch HDD manufacturing equipment |url=https://www.cnet.com/news/toshiba-to-acquire-western-digitals-3-5-inch-hdd-manufacturing-equipment/ |access-date=30 May 2018 |work=CNET |date=28 February 2012}}

In December 2013, Western Digital stopped manufacturing parallel ATA hard disk drives for laptops (2.5-inch form factor) and desktop PCs (3.5-inch form factor). Until that time, they were last hard disk manufacturer to produce PATA hard disk drives.{{cite web |url=http://www.techpowerup.com/196073/western-digital-to-stop-shipping-pata-hard-drives.html |title=Western Digital to Stop Shipping PATA Hard Drives |website=TechPowerUp |date=December 23, 2013 |access-date=December 22, 2014}} Furthermore, they were the only manufacturer that had 250 GB and 320 GB in 2.5-inch form factor.

In February 2014, Western Digital announced a new "Purple" line of hard disk drives for use in video surveillance systems, with capacities from 1 to 4 TB. They feature internal optimizations for applications that involve near-constant disk writing, and "AllFrame" technology which is designed to reduce write errors.{{cite web |title=WD says its new Purple hard drives are optimized for 24/7 video surveillance |url=http://www.pcworld.com/article/2100347/network-storage/wds-new-purple-hard-drives-optimized-for-24-wd-says-its-new-purple-hard-drives-are-optimized-for-24.html |website=PC World |publisher=IDG |access-date=1 October 2016 |date=2014-02-25}}

In November 2020, Western Digital produced a new consumer SSD, the WD Black SN850 1TB. Using a proprietary NVMe version 1.4 controller ("G2"), it is reported to outperform Samsung's 980 Pro 1TB as well as other, new-to-market SSDs containing the Phison E18 controller that arrived after the SN850 became available. The only higher-performing SSD at that time was Intel's Optane line, which is a non-consumer, workstation/server-based SSD with a cost of over five times the SN850.{{Cite web |url=https://pcper.com/2020/11/so-long-samsung-hello-wd-black-sn850/ |title=So Long Samsung, Hello WD Black SN850 - PC Perspective |date=November 9, 2020}}{{Cite web |url=https://www.thessdreview.com/our-reviews/nvme/wd_black-sn850-pcie-4-nvme-ssd-review/3/ |title=WD_Black SN850 PCIe 4.0 NVMe SSD Review – Vying for That Top Spot |date=November 19, 2020}}{{cite web |url=https://www.tweaktown.com/reviews/9664/wd-black-sn850-1tb-nvme-2-ssd/index.html |title=WD Black SN850 1TB NVMe M.2 SSD Review {{!}} TweakTown |date=November 9, 2020}}

In February 2022, Western Digital and Kioxia reported that contamination issues have affected the output of their flash memory joint-production factories, with WD admitting that at least 6.5 exabytes of memory output being affected.

WD experienced a cyberattack breaching the company's systems on March 23, 2023. On April 2, the company proactively took some services offline, including My Cloud, to examine the extent of the intrusion. The attackers allegedly exfiltrated around 10 TB of data from the company, including customer information, and demanded a ransom of "minimum 8 figures" to not publish the data.{{cite web |last=Franceschi-Bicchierai |first=Lorenzo |date=April 13, 2023 |title=Hackers claim vast access to Western Digital systems |url=https://techcrunch.com/2023/04/13/hackers-claim-vast-access-to-western-digital-systems/ |website=TechCrunch}}{{cite magazine |last=Kan |first=Michael |date=April 13, 2023 |title=After 10 Days, Western Digital's My Cloud Finally Restored Following Hack |url=https://www.pcmag.com/news/after-10-days-western-digitals-my-cloud-finally-restored-following-hack |magazine=PCMag}}

Lawsuits have been filed against various manufacturers including Western Digital,[http://www.betanews.com/article/Western-Digital-Settles-Capacity-Suit/1151510648 Western Digital Settles Capacity Suit], betanews.com related to the claimed capacity of their drives.
