The CD/DVD connection is NOT designed to be used with a hard drive, as the performance is very slow.  You will notice the problem even more using an SSD.  Sorry, but this is not a workable option for replacing the optical drive with an SSD -- and there is nothing you can do to speed up the interface to the SSD.
