SATA cable assemblies increase the bandwidth between external storage and other PC components at data transfer rates peaking at 250MB/sec & at speeds from 1.5 to 3 Gbit/sec. SATA cable assemblies are available with 7 terminals to handle serial bus signal or 15 terminals for different source of voltage to power up the device.

The new SATA cable assembly standard replaces the old 26 position ribbon connector with two small flexible cable assemblies for signal and power applications. The SATA cable assembly connector can be hot plugged to motherboards and back planes like the current SCSI standards eliminating the need for ribbon cables.
