Seagate Technology Holdings Plc

A maker of hard disk drives and storage systems, Seagate builds the high-capacity drives that power data centers and edge devices, with products ranging from 1TB to 44TB for uses like gaming, NAS, and cloud storage. Founded in 1978 as Shugart Technology by Alan Shugart and colleagues, it renamed itself Seagate to avoid a trademark clash with Xerox. Its 1980 ST-506 was the first 5.25-inch hard drive for personal computers, shrinking drives from refrigerator-sized machines to fit a desktop.
