This S-ATA 300 cable allows you to easily connect a hard drive, SSD or optical drive to the motherboard of your computer or laptop. The connectors have a flat design and the cord is thin, making the cable easy to hide and not affecting the ventilation in the case. In addition, this cable has metal clips on the connector that keep the cable firmly in place in the connection port. The cable supports a transfer speed of 3.0 Gb/s. This version is also called S-ATA 300 or S-ATA II.
