So basically your advice for identifying the cable is to read what it says on it...awesome

If i replace my current sata cables for these new,it should improve performance?

looks like they separated the RX and TX

I wasn't even aware, who would even read stuff on cables that were handled a large number of times before. Not me, definitively.

Hardly, I think it is a good piccy, I myself havn't handled 6gig cables yet, but seeing this I can visually recognise them from a distance without even reading anything on them, the split cable as highlighted by the piccy is a huge visual indicator to help identify them.

Is the split cable even indictive of 6gb or is it just the way the manufacturer chose to make it look? Ive seen alot of cables look alot of different ways

yep you are right you can get round ones etc. without the obvious insulation split.

Only if you've got compatible drives (6gb/s) and the ports they're being plugged into are Sata 3.0

Huh? How would they be handled a large number of times, do you buy yours used at a flea market?

Hello!!!
I have asus rampage 3 extreme can You tell me how to connect cable 6gb/s is it ok if I plug into Marrvell Serial ATA 6.0 gb/s.
Is it posible to use Marvel for CD/DVD rom ?
Thanx

Only if the Drive supports 6gb, if not then it would it will still run at normal sata speeds, Sats 6gb only improves load times, if your looking into getting more FPS in games, this wont give you any performance in games.
