This Monoprice 18inch SATA 6Gbps Cable w/Locking Latch is a SATA III cable with straight plugs on both ends. Physically, the cable is identical to previous revisions but SATA II and SATA I have less bandwidth, 3 Gbps and 1.5 Gbps respectively. SATA III is what you should go with to attach your hard drives and SSDs to your motherboard or controller. The locking latch mechanism secures the connections between the two attached devices. The cable comes in a red color that would look great in any build.
