Will I experience any significant performance issues if I attach my IDE CD and DVD writers to my motherboard via a 40 wire IDE cable instead of an 80 wire one?

Yes you will. 40 wire cables will not allow the drive to operate faster than 33MB burst speed and may cause the burning programs to fail or at least be much slower.

Why would you want to do that? Modern optical drives run at 66MB burst speed. Look at the link below for a primer on this topic.

I am using an MSI P55-GD55 Motherboard and the single IDE connector is way on the bottom. Even after positioning the two optical drives as close as possible in the tower, the cable is extremely taut . I have a 40 wire Ide cable that is somewhat longer which would alleviate this problem, however, if performance is an issue, I will resolve it a different way. Thank you for your response.

Buy longer round shielded cables. Below is a link to a supplier for a 24" round cable which should work for you. I have used IDE cables up to 36" but shielded. With optical drives signal delay shouldn't be an issue at all.
