Western Digital Corporation, US data-storage maker headquartered in San Jose, California. Its enterprise nearline hard-disk drives ship under the Ultrastar brand, a line carried over from the HGST (Hitachi Global Storage Technologies) business acquired in 2012; Ultrastar DC HC-series drives use HelioSeal helium filling and CMR recording. Part-number pattern (verified 2026-10-22 across multiple sources for WUH722016CLE604): W=Western Digital, U=Ultrastar, H=HelioSeal, ordering code: W=Western Digital, U=Ultrastar, H=HelioSeal, 72=7200 RPM, capacity digits follow, L=26.1 mm standard height, E6=SATA 6 Gb/s 512e, trailing digits=encryption option. Not the YMTC or CXMT controlled-brand group. Evidence retrieved 2026-10-22 from independent storage-trade articles and distributor listings decoding the Ultrastar ordering code.
