SATA is a popular standard for connecting and powering computer data storage devices. It is much smaller than the deprecated IDE while allowing much higher data transfer rates. Slimline SATA is a smaller SATA connector for smaller or slim form-factors, such as notebook optical drives. These particular SATA cables have a Slimline SATA power to Molex (4-pin) interface that is especially useful with power supplies having no or not enough Slimline SATA power cables, allowing you to use notebook optical drives with desktop, workstation, and server computers. SATA cables are an absolute necessity for any SATA-capable computer system, and with our SATA cables, you can take full advantage of your SATA devices' ultra-fast data transfer capabilities.
