LSI SATA 150 1.2.1Hardware and Software Characteristics, Table, SATA 150 Board Characteristics

–Use a low-cost 7-pin connector with thin, flexible cables

–Use low voltage signaling levels to reduce current draw, EM emission, and signal switching time

•PCI Specification, Version 2.2:

–Backward compatible with previous implementations of the PCI specification

–SATA 150-6 and SATA 150-4 boards conform to half-size PCI form factor. SATA 150-2 board conforms to low-profile PCI form factor.
