History
The brand was originally introduced by IBM in 1994 for enterprise-level HDDs together with home-computing oriented Deskstar model. These drives were based on revolutionary metalized glass disk technology. In 2003 IBM's HDD business was acquired by Hitachi, reorganized as Hitachi Global Storage Technologies(HGST) which was sold, splitting the business between Western Digital and Toshiba in 2012. The part acquired by Western Digital has retained the "HGST Ultrastar" brand name. Western Digital continued using the HGST prefix on product labels, slowly phasing it out. This resulted in that some models were sold under both HGST and WD branding simultaneously (e.g. the HGST Ultrastar He10 and WD Ultrastar HC510 are the same models of HDD).{{Cite web|title=Product Manual: Ultrastar DC HC510 (He10) OEM Specification - SATA models|url=https://usermanual.wiki/m/ccceae2436e06fa7d0f4c1e117c6c4da9ee65ef55a331cf5c72e2ab624e548e7|access-date=2021-10-11|website=UserManual.wiki|language=en-US}}
These drives are typically used with enterprise computer systems. The two 1994 models, the 10.8 GB Ultrastar2 and the 8.7 GB Ultrastar2 XP were offered with a variety of interfaces including Fast SCSI, Fast-Wide SCSI, SCA 80-pin connectors, and Serial Storage Architecture. Evaluations units were available in the third quarter of 1995. {{cite book |url= https://books.google.com/books?id=ZDgEAAAAMBAJ |title= IBM's disk drive family has three new members |last=Francis |first=Bob |page=40 |date=October 17, 1994 |publisher=Infoworld |access-date=May 23, 2021}}
