BitFenix Sleeved Cables use a textile sleeve. This is significantly higher quality than the usual plastic versions, very tight woven, completely opaque and flexible. This is a 75 centimeter long SATA 6G (SATA III / SATA 3) data cable with black sleeve and black connectors, which is used between motherboard and HDD/SSD. The connectors are not compatible with eSATA. In order to achieve the desired optical effect, the other cables in your build should also be replaced by corresponding BitFenix cables in the same color.
