Still using an ancient Zip disk or CD-R for PC backups? It's time to enter the twenty-first century and move up to a recordable DVD format. These days, combination 4x DVD drives, which support at least DVD-R, DVD+R, DVD-RW, and DVD+RW (some also support DVD-RAM) are selling for just over $100, and that price—combined with their 4.7GB capacity—makes them a no-brainer. And don't worry, recordable CD fans, the recordable DVD drives will still work with and record your existing CD-R and CD-RW disks just fine
