IDE cables are usually grey and about 2" wide and SATA cables are only about half an inch wide . Look at the cables coming from your HD and if they are the same as your DVD drive they are SATA if they are the wider type then they are IDE .
The Sony
is an IDE drive, I suspect the other drive will also be IDE.
It don't matter that much whether the DVD/CD drives are IDE or SATA, they are by their nature "slow" drives. Once they "spin-up-to-speed" then there should be no noticeable slow-down ... that again depends on what you, or your PC, is doing at the same time, and what information is being sought from the drive.
I can send you two CDs, one will give you no problems, the other will, hiccup, stutter even stop, but will eventually "play" with enough cajoling ...
There is a big difference between DVD & CD "speeds" as in a 16x CDRom drives has no relation to a 16x DVD drive ...
