During the initial period after SATA 1.5 Gbit/s finalization, adapter and drive manufacturers used a "bridge chip" to convert existing PATA designs for use with the SATA interface. Bridged drives have a SATA connector, may include either or both kinds of power connectors, and, in general, perform identically to their native-SATA equivalents. However, most bridged drives lack support for some SATA-specific features such as NCQ. Native SATA products quickly took over the bridged products with the introduction of the second generation of SATA drives.
