NEW 18" SATA (Serial ATA) 150 MByte/s Computer PC Data Cable

150 MByte/s maximum transfer rate Length: 18 inches Hot-plugging capability Tagged command queueing Seven-wire data cable. Connectors measure just 8 mm wide. About Serial ATA Lower Voltage - Parallel ATA is based on TTL signaling, requiring integrated circuits to tolerate input signals as high as 5 volts. Soon, integrated circuits manufactured on the leading manufacturing processes will not be able to efficiently support 5 volt signaling voltages. With the upcoming fine lithographies, it will not be practical to support 5 volt signaling tolerance. Serial ATA manages this by reducing signaling voltages to approximately 250 millivolts (0.25 volt).   Pin Efficiency - Currently, the parallel ATA interface has 26 signal pins going into the interface chip. Serial ATA uses only 4 signal pins, improving the pin efficiency and accommodating a highly integrated chip implementation.   Improved Cable and Connector Plant - The current parallel ATA cable and connector are bulky, made up of
