Is there a difference between SATA II and SATA III Data Cables?
Not really, except that the SATA III specs require the connectors to have latches.
This prevents the cables from being accidentally disconnected when the computer is moved around.
You should definitely make sure your SATA Data Cables comes with Latches.
Just make sure to pinch the Latch down hard before attempting to pull out a SATA III Data Cable.
