Western Digital Corporation
A maker of hard disk drives and storage products that keep data safe, from cloud data centers to home computers. Founded in 1970 as General Digital Corporation, it started out making calculator chips before pivoting to storage, renaming itself Western Digital in 1971 for a "broader industrial identity." It later absorbed flash-memory maker SanDisk, and today its drives power hyperscale data centers, PCs, and external storage sold in retail.
