How to determine a cable is SATA 2 or 3?

[AlphaLion]

In my motherboards' box i found 2 types of SATA cables intact, 2 blue and 2 red. I red lots of stuff to know which is SATA 3 and which is 2, but i couldnt find any useful information except this picture. But all 4 looks the same, the blue ones were in my current motherboard which supports SATA 3 and the text means 6Gbps/3Gbps so i guess that is SATA 3. The red ones dont have any info like this, SATA number either. How can i know they are SATA 2 or 3 cables? Picture

I've answered this many times in the past.

All SATA cables are the same except in quality - - they are just SATA cables. The different colours mean nothing - - just depends on the factory which made them. Some PC owners may prefer red or blue to match the other cables in the system case.

SATA, SATA II & SATA III refers to the SATA controllers/connectors on the motherboard, not the cables.

You can use any of those cables for any SATA speed.

Now, you may see some cables advertised or packaged as "SATA II" or "SATA III" but that is just a trick used by some manufacturers or vendors to charge more money for them. A SATA cable is a just what it is - - a SATA cable.
