How to Purchase a Computer DVD Burner

DVD discs are the ultimate means of storing data- holding several CDROMs worth of data, in the same space as a regular CDROM media. There are several specifications and features to keep in mind when purchasing a DVD burner. Space considerations, drive compatibility, and storage requirements are the most important features of a drive. If you select a computer DVD burner based on these areas, your DVD recorder will not become obsolete as easily as a drive which is purchased based on a low price.

DVD CD burners are usually available either in single layer, or with a dual layer support. The difference between these two formats is the storage ability of the drive. In a single layer format, only 4.7 GB of data is able to be stored on the disc. With the dual layer format, 8.5 GB of data can be stored on a single DVD disc. If you wish to use your DVD burner to create backups of DVD movies, you will need the 8.5 GB of space that the dual layer technology offers. Dual layer drives are backward compatible with single layer discs. When you are looking for a DVD burner for your PC or Mac, choose a drive that supports dual layer discs, or both formats.


In addition to the single layer/dual layer formats, there are two different types of DVD discs, plus (+) and minus (-). The plus (+) discs were primarily available for speed, since they were faster than minus (-) discs when first released. However, that speed gap has since been closed, and there are no speed issues between the two formats. The main reason to use minus (-) discs is because minus (-) discs will play better on most DVD players, offering the most compatibility. There is not usually a price difference between the two formats, and most DVD burners can burn both formats. Keep this in mind when selecting any computer DVD burners.


Finally, the drive's speed and size should be considered for when selecting any DVD burners for computers. If the burner is for a laptop or a flat notebook, select an external, USB 2.0 portable powered burner. If the burner is for a desktop computer, consider selecting an internal DVD burner as your solution. External burners are typically slower during burning and more expensive than internal burners. This decrease in drive speed is due to the interface, as well as the design of the unit. Since the computer hardware manufacturer concentrates more on decreasing the physical footprint of the unit, speed usually suffers as a result. Keep this problem in mind when you are selecting a DVD burner for a laptop or desktop computer.


When selecting a DVD burner, keep these three main differences in mind, as they will help you determine which drive will best fit your needs. Whether you purchase your drive from manufacturers such as Pioneer, DELL, Compaq, HP, Toshiba, Gateway, Sony, Acer or other common brands keep these three key differences in mind, you will probably have purchased a drive that will not become obsolete, then a drive which was purchased simply because it was on sale.
