The HP 1TB 3.5" FATA drive (671148-001/AG691A/454414-001) uses the FATA interface (Fibre Attached Technology Adapted), which integrates SATA drives into storage arrays via an FC-compatible connection. This technology was mainly used in HP StorageWorks systems to make lower-cost SATA capacity usable in FC SAN environments. It suits expanding or maintaining corresponding HP storage arrays.
