Today we will be reviewing an external DVD Burner from LiteOn. The SLW 831SX is a slim external drive, mainly targeted at notebook users, who need to make backups or burn the occasional CD or DVD, and don't care about the low speeds that such a solution offers. The 831SX offers 8X for both DVD+R and DVD-R formats, while it also supports DL writing, even though this is done at the lowest available writing speed of 2.4X. RW formats are also supported at the 4X burning speed. As far as the CD media is concerned, the drive offers 24X burning speed for both CD-R and CD-RW media.
Throughout these pages, we will see how the drive performed with a variety of media, in order to check the drive's Reading, Writing, Error Correction and Ripping capabilities.
