|If your computer originally came with a CD ONLY writer then it must be fairly old. You probably don't have any SATA ports to connect a SATA DVD drive to.|
They will both perform the same. The criteria is which type of connection is available on your motherboard. If you would find it necessary to connect an IDE optical drive to the same cable as your main hard drive and you have a SATA connection available then use SATA.
IDE is an older technology that is being phased out in favor of SATA.
