Recording or capturing video is probably the most hard drive intensive activities that your computer can perform. Knowing that, I would record footage to your fast drive and put WoW on your 7200 rpm drive.

Another thing that would help tremendously... defragment your fast harddrive before recording to it. Everytime I start a new video project, I defrag my drives. That may seem a bit too anal, but if you analyze your drive with a defrag tool after you record to it, you'll see just how messy it can get after only one video project (which can really slow down the drive's I/O).
