About Western Digital
Western Digital makes hard disk drives and storage systems, covering data center drives under the Ultrastar name and consumer lines such as WD Blue, WD Red and My Passport. It was founded in April 1970 in Newport Beach, California, and is headquartered in San Jose. On February 24, 2025 it spun off its flash memory business as Sandisk, leaving Western Digital focused solely on hard disk drives. It is a storage supplier rather than a processor maker, and its drives hold the large datasets that AI and cloud compute systems read from.
Western Digital was founded in 1970 and is based in San Jose, California, United States. It is listed under Custom Silicon, Memory & Storage. Its shares trade as WDC on NASDAQ.

What Western Digital works on
Custom Silicon
Custom silicon means a company designs its own chips for its own products or data centers instead of buying standard parts. The chip is made by a foundry such as TSMC, but the design belongs to the customer.
Memory & Storage
Memory and storage hold the data that processors work on. Memory such as DRAM is fast and loses its contents when power is removed. Storage such as flash (NAND) is slower, cheaper per bit and keeps data without power.
