Review on CableCreation 3 3FT External SFF 8644 Cable by Brett Gilbert

As another reviewer said, the cable doesn't stay in its connector. 10GTek makes a similar cable for about the same price, but it plugs securely into the port. I'm not sure if my cable is "broken" (that doesn't mean I'm abusing the cable), but you probably don't want SAS cables falling out of your hardware.
