I know I'm old, but I always keep an internal writer. They cost nothing, and blank DVDs/Blu-Ray are disposable at this point. It's way too easy to get beat for a USB drive, happens all the time.
I'm 43, but when I built my PC this year I figured it wouldn't need one.
Come to think of it, maybe I should get a Blu ray burner and not just DVD. Who knows of I'll ever need it, but might as well since I'm getting one.
