Seagate Technology Holdings plc is an Ireland-incorporated storage company with executive offices in Singapore and major operations in the United States, Northern Ireland, Thailand and China. It builds the spinning magnetic drives that hold most of the bulk data in cloud data centers, along with drives for surveillance, NAS, PCs and gaming. Founded in California in 1979, it has outlasted dozens of disk-drive rivals and now shares the HDD market with Western Digital and Toshiba. The company is headquartered in Fremont, California.
Seagate makes money by selling storage hardware. The largest piece is mass-capacity storage: nearline Exos hard drives sold to hyperscale cloud providers, enterprise OEMs and data center operators, plus drives for video surveillance and NAS. Customers buy on cost per terabyte, power per terabyte and reliability, so each new generation of higher-capacity drives, now HAMR-based Mozaic platforms, lets Seagate sell more exabytes per unit of factory capacity. A smaller legacy business sells client and consumer drives (BarraCuda, FireCuda, external drives), and Seagate also sells enterprise SSDs, storage systems and Lyve data services. Cash is returned through a quarterly dividend, $0.74 per share as of the October 2026 payment, and share buybacks.
