EZQuest has introduced the Fast Boa 8x Dual-Format DVD-RW/+RW external drives at Macworld Expo.

The new drives write to DVD+R and DVD-R at 8x; DVD+RW and DVD-RW at 4x; CD-R at 24x; and CD-RW at 10x speeds. They also read DVDs at 12x and CDs at 40x.

According to EZQuest, the devices feature new technology that offers "very reliable" recording during high-speed writing; "precise recording" onto warped or uneven discs; auto-adjustable writing that "minimizes deterioration" of DVD-RW discs; and "enhanced stability" during high-speed recording and playback.

EZQuest president Ebrahim Zmehrir said: "Boa 8x drives are complete solutions for authoring video or music, transferring files from one computer to another, and backing up or archiving data. They're fast, they're compatible with all DVD+, DVD- and CD media, and they come ready to plug in and start burning."

Two versions of the Boa 8x FireWire are available. A $249 version includes Toast Lite and Dantz Retrospect Express software, a $299 version features Toast Titanium in addition to Dantz Retrospect Express.

A USB 2.0 model is also available for $249 and is bundled with Sonic My DVD and Dantz Retrospect Express. UK pricing is to be confirmed.
