How to Buy a Rewritable DVD Drive
Introduction
All the talk about the next wave of optical formats--Blu-ray Disc and HD DVD--might make you think that the venerable DVD-Rewritable drive is passé. Not so fast: DVD burners, and the media you use with them, remain a vastly less expensive option for writing discs than those costly new formats. Plus, you can get superior performance from a dedicated DVD burner: The write speeds top out now at 20X.
Rewritable DVD's advantages over CD-R are long established: Single-layer DVD media lets you store up to 4.7GB on a disc, while dual-layer (also referred to as double-layer, for the DVD+R format) media lets you pack up to 8.5GB on a single disc. Like CD-RW drives, rewritable DVD drives support both write-once and rewritable media; write-once discs are best for creating movies playable on standard DVD players and for data archiving, while rewritable discs are well suited for regular file backup.
