<p></p>Each major revision of the Serial ATA interface specification has doubled the maximumdata transfer rate. The latest SATA Revision 3.0 allows for data transfer speeds of upto 6 Gbps. <br /> <br />While the cables for all three revisions appear to be similar and will physically fitinto the connectors on all SATA drives and controllers, the higher data transfer rate ofSATA 6 Gbps requires higher quality materials and closer tolerances than the previoustwo revisions required. <br /> <br />SATA 6 Gbps cables are certified to provide maximum speeds from your SATA system, upto 6 Gbps when used with equivalent devices and controllers. <br /> <br />One end of this internal cable while the other end uses a which can make for bettercable management in some situations, especially in tight spaces. Each end has anattached locking latch, to ensure that your connections do not come loose due tomovement or vibration. <br /> <br /> <b>Note:-</b> SATA 6 Gbps cables are backwards compatible and can be used with SATA 3Gbps and SATA 1.5 Gbps devices. However, the data transfer of the SATA subsystem will belimited to that of the slowest device. So, for example, if a SATA 6 Gbps cable isconnected to a SATA 3 Gbps drive and a SATA 1.5 Gbps controller, the drive will belimited to a transfer rate of 1.5 Gbps. <p></p>
