You might as well get a DVD burner though since they are so cheap. Many also allow for all DVD formats including Dual Layer.
Some even have DVD-RAM which is basically a slow (about 2x) but a good way of backing up all your data as it acts like a DVD-RW yet can be wiped over around 10,000 times. So they could be used as a drive as it were ( I knew the exact definition at one point)
Most if not all allow for burning off CD-R, CD-RW too which is always a plus so you can throw away your old one, or use it as a straight copier to copy one to the other.
So you might as well, since it'll come in useful sometime in its life
