![]() Noise is another factor to bear in mind when shopping for an external DVD drive. Top-loading drives pop open a lid that allows you to place the disc onto the spindle. A mechanism grips the disc and pulls it inside. Slot-loading drives offer a slot into which you introduce an optical disc. You pop or drop the disc into the tray and then either push the tray closed or press the eject button again. They open in front at the touch of the open or eject button and either extend a motorized tray or pop the entire mechanism forward. Tray-loading, slot-loading, and top-loadingĮxternal DVD drives can load optical discs via a tray, a slot, or by lifting the top.

This is especially true if you run Linux.Īlso, check to see if a drive is compatible with the formats of the optical discs you want to use. While major compatibility issues are largely a thing of the past, it’s still worth double-checking to make sure your external DVD drive is supported by the hardware and operating system you use.

As laptop designs have become ever thinner and lighter, eliminating DVD players and optical drives became one of the easiest ways to drop weight and free up additional space. Now, they are all but an afterthought on many current models, especially among laptops and notebooks. It wasn’t that long ago that optical drives such as CD-ROM readers and DVD players were among the most sought-after features in a desktop or laptop computer. High-end external optical drives can include software that improves reliability when reading discs that have fingerprints or minor scratches. As there’s no sign that built-in internal optical drives will be making a comeback anytime soon, especially in laptops and notebooks, and as tablets and tablet convertibles become more popular and more compatible with external USB accessories, there’s never been a better time to buy an external DVD drive. ![]() Many people have years of backups on DVD-Rs and DVD-RWs, not to mention pictures, media, and older application installers. DVDs are still one of the most popular formats for watching movies.
