Review on Caseling Portable Hard Carrying Travel Storage Case for External Optical Drives - Black by Cristina Wicomb

This is a really well made product. It will do what you want for years. The only possible downside, and it's a small one, is that nowadays an additional DVD drive probably doesn't need the vertical space available in this case to tuck away cables or the like. This can be a blessing in disguise as you can use that space to pack a few other small items (USB sticks, cables or whatever) that would benefit from some protection. Highly recommended
