If you need a longer lifetime for your DVD burner, get 2-year warranty. Some of the LG drives on the market are 2-year-warrantied, depending on the distributor's policy. When manufacturers feel their drives have a very high mechanical failure rate, they are more likely to provide as short warranty period as possible. Some memory vendors advertise "limited lifetime warranty" because they feel their memory modules should last forever or at least longer than CPUs and VGAs residing on the same motherboards.
