Western Digital Corporation has a long history in the electronics industry as an integrated circuit maker and a storage products company. It is also one of the larger computer hard disk drive manufacturers, along with its primary competitor Seagate Technology.
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.
In March 2011, Western Digital agreed to acquire 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.
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 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.
In April 2017, Western Digital moved its headquarters from Irvine, California to San Jose, California. In December 2017 Western Digital reached an agreement with Toshiba about the sale of the jointly owned NAND production facility in Japan. In May 2018 Toshiba reached an agreement with the Bain consortium about the sale of that chip unit.
In May 2016, Western Digital acquired SanDisk for US$19 billion. In the summer of 2017, Western Digital licensed the Fusion-io/SanDisk ION Accelerator software to One Stop Systems. In August 2017, Western Digital acquired Upthere, which offers apps that sync files and photos across devices, with the intention to continue building out the service. In September 2017, Western Digital acquired Tegile Systems, maker of flash memory storage arrays.
In July 2018 Western Digital announced their plan to close their hard disk production facility in Kuala Lumpur.
Self-encrypting Western Digital hard drives have been reported to have severe faults and to be easy to decrypt.
Western Digital was the last manufacturer of parallel ATA hard disk drives for laptops (2.5-inch form factor) and desktop PCs (3.5-inch form factor), producing them until December 2013. Furthermore, they were the only manufacturer that have 250 GB and 320 GB in 2.5-inch form factor.
Western Digital sells data center software and system solutions. Including an enterprise-class Ultrastar product line. In October 2017, Western Digital shipped the world’s first 14 TB HDD, the helium-filled HGST Ultrastar Hs14.
Western Digital sells consumer storage products under the WD brand, with product families called My Passport, My Book, WD TV, and My Cloud. While traditionally these products have used HDDs, Western Digital has started to offer SSD versions, such as the My Passport SSD, its first portable SSD. In September 2015, Western Digital released My Cloud OS 3, a platform that enables connected HDDs to sync between PCs and mobile devices.
Western Digital also sells consumer data technology products under the SanDisk, and G-Technology product brands, as well as cloud storage services under the Upthere brand. Through Western Digital’s acquisition of Upthere, the company offers personal cloud storage through the Upthere Home app and UpOS operating system.
Under the SanDisk brand, Western Digital offers mobile storage products, cards and readers, USB flash drives, SSDs and MP3 players. Most of Western Digital’s consumer flash memory products are offered through SanDisk. The SanDisk iXpand product family, including the iXpand Flash Drive and iXpand Base, is made specifically for use with the Apple iPhone and iPad. The 400GB SanDisk Ultra microSDXC UHS-I card was designed primarily for use in Android smartphones that include an expansion slot.
Lawsuits have been filed against various manufacturers including Western Digital, related to the claimed capacity of their drives. The drives are labelled using the convention of 103 (1,000) bytes to the kilobyte, resulting in a perceived capacity shortfall when reported by most operating systems, which tend to use 210 (1,024) bytes to the kilobyte.
While Western Digital maintained that they used "the indisputably correct industry standard for measuring and describing storage capacity", and that they "cannot be expected to reform the software industry", they agreed to settle in March 2006, with a $30 refund to affected customers in the form of backup and recovery software of the same value.
