Every three weeks, we host a Stock Battle on our X page between two competing companies. Which one is the favorite of our followers? And find out which one we believe has the stronger fundamentals.
This round brings you Seagate Technology vs. Western Digital — two leading players shaping the backbone of global data storage. Both stocks have skyrocketed this year: Seagate +128% YTD and Western Digital +113% YTD 🚀 — making them the top performers in the entire S&P 500!
Both now focus purely on hard drives, forming a duopoly in the HDD market.
But which one deserves the crown in data storage? 👑
Seagate and Western Digital have been in storage for decades — but they’ve taken different paths.
Seagate Technology, founded in 1978, built its name on hard disk drives (HDDs). It still focuses on high-capacity drives that power cloud and datacenter storage. To handle ever-growing data from AI, video, and cloud services, Seagate keeps advancing HDDs with innovations like HAMR. With its Mozaic 3+ platform, it’s preparing the next generation of ultra-high-capacity drives — pushing storage technology forward.
Western Digital, founded in 1970, also started with HDDs. For years, it combined that with a large flash business thanks to its 2016 SanDisk acquisition. But in February 2025, Western Digital officially split into two separate companies: Western Digital for HDDs, and SanDisk for flash and SSDs. Western Digital is now a pure-play in hard drives, more focused, but also more dependent on a mature market.
Both ride the same long-term driver — the steady growth of global data. It’s not as flashy as AI chips, but without storage, none of those workloads could exist.
