## Summary

Western Digital (WDC) reported ~$13.0B revenue in FY2024. Leading maker of hard disk drives and NAND flash storage products for cloud data centers, PCs, and consumer devices. HQ: San Jose, CA.

## Company Overview

Western Digital Corporation is one of the world's largest data storage companies, manufacturing hard disk drives (HDDs) and NAND flash memory (under the WD and SanDisk brands) used in cloud data centers, personal computers, mobile devices, and enterprise storage systems. Founded in Santa Ana, California in 1970, Western Digital has survived multiple technology transitions and industry consolidations to become one of only two remaining large HDD manufacturers (alongside Seagate) and a major participant in the NAND flash market.

Western Digital reported approximately $13.0 billion in revenue in FY2024, with its business split between the Cloud segment (high-capacity HDDs for data center operators like AWS, Azure, and Google), Client segment (PC and laptop storage), and Consumer segment (external hard drives, flash cards). The company has been working to separate its HDD and NAND flash businesses into two independent publicly traded companies — a spinoff that would allow each to optimize its capital structure and strategy independently. HDDs and NAND flash operate on very different economic cycles and competitive dynamics, and investors have long viewed separation as value-unlocking.

The long-term HDD market is increasingly concentrated in cloud data centers, where hyperscalers are installing massive high-capacity drives (16TB, 20TB, 26TB+) to store the exponentially growing volumes of AI training data, video content, and enterprise information. This "mass capacity" HDD segment is growing despite the shift of client PCs to SSDs, as HDDs remain the most cost-effective storage media per terabyte for cold and warm data workloads.

## Frequently Asked Questions

### What does Western Digital make?
Western Digital makes hard disk drives (HDDs) under the WD brand and NAND flash storage under the SanDisk brand, used in cloud data centers, laptops, mobile devices, gaming consoles, and surveillance systems.

### What is Western Digital's planned spinoff?
Western Digital has been working to spin off its NAND flash business (SanDisk) from its HDD business into two separate publicly traded companies, allowing each to operate with an optimized capital structure and focused strategy. As of 2024, the transaction was still in process.

### What is Western Digital's ticker?
Western Digital trades on the Nasdaq under the ticker WDC.

### Why are HDDs still relevant despite SSDs?
SSDs are much faster but far more expensive per terabyte. Cloud data centers store vast amounts of infrequently accessed ('cold') data where speed matters less than cost — making high-capacity HDDs the economical choice for archive, backup, and bulk object storage workloads.

### What is Western Digital?
Western Digital is a leading data storage company manufacturing hard disk drives (HDDs) and NAND flash-based solid-state storage, serving cloud data centers, enterprise customers, and consumer markets under the WD and SanDisk brands.

### What is Western Digital's strategic split?
Western Digital separated its HDD and flash businesses in 2024, spinning off its NAND flash and SanDisk brands as a separate public company, allowing each business to pursue independent capital allocation and strategic focus.

### What is Western Digital's revenue?
Western Digital generates approximately $13B in annual revenue, trading on NASDAQ under ticker WDC, with revenues split between HDD (enterprise nearline, desktop, surveillance) and flash (SSD, embedded, mobile) segments.

### How does Western Digital benefit from AI demand?
Western Digital's nearline HDD business benefits from AI data center buildout for training data storage, while its flash business benefits from AI inference requiring low-latency SSD storage in GPU servers — making WD a dual beneficiary of the AI compute buildout.
