This particular model is from SYba with the Silicon Image 3512 chipset. It has 2 ports that can be used as RAID. But this controller will need to have the BASE BIOS from Silicon Image website flashed in order for the SATA optical drive(s) to work properly. However, you should check with your local store to make sure it's returnable if the Flash chip cannot be flashed.
Your current IDE drive(s) will work irregardless of the controller card, so no need to get a SATA -ROM drive.
SATA "I" should work fine, but having SATA "II" doesn't hurt. Can't tell what chipset the Masscool card has, but anything with VIA doesn't work well with SATA optical drives. Best bet is to use Silicon Image-based chipsets. Check my signature for a list of some compatible cards (old and new).
