<b>What do these do and would it be recomended that i get one if is was buying a YAHAMA 16x/10x/40x burner?</b>
Yes, ATA100 is backward compatible.
<b>Would it help the speed of my computer if i had my hard drive hooked up to one?</b>
In my experience, I see increasing performance (~5%)when I hooked up my IBM Deskstar ATA66 into ATA100 controller.
