YW. I don't think any of those combo cables have the metal clips for some reason probably because they are using the notebook SATA/power connectors which don't have them either.
I got some of those new Silverstone SATA cables, but the testing I've done don't show them to be any better than the other SATA 2 rated cables - my controllers are only SATA 150 anyhoo. One way to improve SATA cables would be to make them more flexible... Newegg is listing them at a dollar OVER MSRP right now... Tsk, tsk!
