The 840 series of drives is Sony’s latest crop of multi-format DVD burners that support 20X DVD±R recording speeds, delivering a full 4.7 GB disc of video, data, music or images on standard 16X DVD+R media in about five minutes. In addition, the drives can record on 8.5GB DVD+R Double/Dual layer and 4.7GB DVD+RW discs at 12X speed.
The internal DRU-840A drive and external DRX-840U burner come bundled with the Nero® 7 Express DVD/CD mastering software. The new DRX-S70U burner has a slim design to compliment a notebook or desktop PC, supports 8X DVD±R recording speeds, and comes with a full version of the Nero 7 software suite. All three burners support both dual and double layer formats, as well as CD-R/RW recording.
The internal DRU-840A drive incorporates an ATAPI interface for easy installation inside a PC, and includes a black replacement bezel for matching to black-colored PC cases. The external DRX-840U drive features a space-efficient vertical design and offers connectivity with a high speed USB (USB 2.0) digital interface for simple setup.
Both models support 20X DVD±R, 12X DVD±R DL, 12X DVD+RW, 6X DVD-RW, and 12X DVD-RAM for data backup, as well as 48X CD-R and 32X CD-RW recording speeds.
Any bets as to the read manufacturer? I'm betting its a Samsung design. Maybe the SH-S202 or a crippled SH-S203?
