I bought a couple of these a while back. Used them with my IDE drives to run sata raid0. Worked great. What I really want to try though is to use these on a CD rom or burner, or DVD rom or burner. They will work with these atapi devices. However you need a sata controller that will recognize them. So far as I know, only the SI built-in controller will do this. I have an ABit NF7-S coming in in a couple of days (it has the SI sata controller) and I'll try it out.
