This slick Serial-ATA cable set offers four blue independent SATA cables rounded into one convenient, easy to use, cable bundle. With benefits such as improved chassis airflow and a neat, tidy and professionally cabled look for your system, this cable set features right angle connectors on the drive end and straight connections on the motherboard or SATA expansion card end, making this cable set the perfect solution for chassis with up to four SATA connector drives. These cables offer transmitting speeds of 3Gbps and the length of the four cables are 850, 810, 770 & 730mm respectively. Whilst this cable set was designed for SATA II drives with 3Gbps, it is also backwards compatible for SATA I drives and will cause no data errors with older SATA HDDs or optical drives, such as DVD burners.
