Each major revision of the Serial ATA interface specification has doubled the maximum data transfer rate. The SATA Revision 3.0 allows for data transfer speeds of up to 6 Gbps.
While the cables for all three revisions appear to be similar and will physically fit into the connectors on all SATA drives and controllers, the higher data transfer rate of SATA 6 Gbps requires higher quality materials and closer tolerances than the previous two revisions required.
Monoprice SATA 6 Gbps cables are certified to provide maximum speeds from your SATA system, up to 6 Gbps when used with equivalent devices and controllers.
Each end of this internal cable features a straight connector with an attached locking latch, to ensure that your connections do not come loose due to movement or vibration.
