I've just bought a Crucial 128GB C300 SSD drive for my Dell Precision 5400.
The PC has 3Gb/s SATA interfaces on the motherboard and the drive has a 6Gb/s SATA interface. Is it safe enough to use a cable rated for 6Gb/s in this configuration.
The reason I ask is that in the dim and distant past (possibly with SCSI) I've had experiences before where using higher rated cables have had a detrimental effect on performance because the electrical characteristics are different from what the controller expected, even though it's a better cable.
