I bought a sata cable recently from newegg because I needed a 6gbit/s (SATA III) cable for a new SSD I bought. After purchase I realized it looked exactly the same as the two Sata 3gbit/s cables that came with my motherboard. The two 6gbit/s are labeled as such, but the 3gbit/s have no labeling other than standard labeling on cable. I looked at newegg and the Sata type was "SATA II" but the description of the cable says it can handle 6gbps (as well as 3 and 1.5gbps). I thought SATA III meant 6gbit/s and SATA II meant 3gbit/s limit. How does a SATA II type cable able to have 6gbit/s limit/compatibility?
Edit: Little more information. My motherboard (P7P55D-E) Came with 2x Sata 6gbps and 2x Sata 3gbps (Says so in parts list of manual). The 6gbps are labeled as such, the 3gbps look like ordinary black sata cables. The new cable I bought that says it can handle 6gbps looks like the 3gbps ordinary cable i got with my motherboard and does not state 6gbps on the cable. It is type "Sata II" in newegg but states it can handle 6gbps. How does this make sense? I am confused.
