DVD drives can turn a computer into a personal entertainment system. There are a variety of different models on the market in a wide price range. DVD drives that merely play are usually the cheapest and drives that can burn DVDs onto blank discs as well as play both commercially produced and burned DVDs usually cost more. For fast DVD copying, you'll want at least two DVD drives so that while you're pulling information from one you can instantaneously burn it onto another rather than have to save it to a file and burn it once you take the original DVD out.
DVD Combo Drive
A DVD combo drive is the drive that will both play and burn DVDs. You can purchase DVD burners separately if you choose. One benefit to having a separate DVD burner is that it's less wear and tear on the DVD drive you used to play DVDs. Dual DVD drives allow you to play DVDs as normal, but you can also rip from one and burn to another in one smooth process.
You can purchase slim DVD drives that are designed to take up less space on your desk, or you can purchase internal DVD drives that are installed inside your computer case and hook directly into your motherboard. External DVD drives are the easiest for people who aren't comfortable opening their computer case and attaching anything internally. They only need to be hooked into the computer, usually through a USB cord, and can be used just like an internal drive. This makes it easy for anyone to purchase and use a DVD drive.
