Due to the date of this testing and the fact that this question still comes up fairly often we have decided to revisit this topic with more modern hardware in our sata 3gb s vs.
Sata 3gb 6gb cable difference.
6gb s cable performance revisited article.
The bandwidth throughput which is supported by the interface is up to 300mb s.
Sata ii revision 2 x interface formally known as sata 3gb s is a second generation sata interface running at 3 0 gb s.
On asus supplied cables you can tell by the indent running down the middle of the cable gigabyte supplied cables don t have this they are just a little thicker than their old.
Sata was announced in 2000 in order to provide several advantages over the earlier pata interface such as reduced cable size and cost seven conductors instead of 40 or 80 native hot swapping faster data transfer through higher signaling rates and more efficient transfer through an optional i o queuing protocol.
Sata 6gb s cables have the transmit and receive data pairs independently shielded.
Our results confirm that despite the faster hardware available today there is still no performance difference between sata 3gb s and sata 6gb s cables.
The sata 3gb s revision only supports transfer speeds around 300mb s yet we saw transfer speeds up to 500 mb s with each cable that we tested.
Revision 1 0 of the specification was released in january 2003.
Sata iii revision 3 x interface formally known as sata 6gb s is a third generation sata interface running at 6 0gb s.
