Overview
Adaptec was an American computer storage hardware company focused on storage connectivity and data-protection equipment. Its products included SCSI adapters, storage adapters, and RAID controllers used to connect storage devices and manage disk arrays in servers, workstations, and other computer systems. Founded in 1981, the company was later acquired by PMC-Sierra. PMC-Sierra was subsequently acquired by Microsemi, after which the Adaptec brand gradually faded from the market. Available material is insufficient to confirm any continuing independent commercial operation, so the brand is classified as defunct.
History
Adaptec was founded in 1981 and focused on computer storage connectivity hardware. As servers and workstations increasingly required external storage connections, SCSI interfaces, and disk-array management, the brand developed a product portfolio centered on SCSI adapters, storage adapters, and RAID controllers. These products connected host systems to storage devices or managed disk arrays for data protection, giving Adaptec recognition in enterprise computing and professional hardware markets. In 2010, Adaptec was acquired by PMC-Sierra, changing the ownership and organizational position of the business. PMC-Sierra was later acquired by Microsemi, after which Adaptec was no longer developed as an independent company and gradually faded from the market. Available information does not establish the founder, headquarters, detailed product models, or exact discontinuation date, so this history is limited to the main confirmed stages.
