You just need two physical hard drives inside your pc if you want to get serious about video/burning dvd's. As you can see by my signature, I have two harddrives in each of my pc's. Some pc's like the newer dell's only have one ide channel, but they have plenty of sata channels. So in one pc I have two sata hd's, and in the other, I have one sata, and one pata drive (it has two ide channels). Another PC I had three separate hd's in one box. Just had to add extra cooling. You don't have to have a 360gb hd, but they are nice. Hell, I could use a couple of 500gb hd's, but I'll wait until I can get them on sale with some good rebates.
