The DVD burners in the iMac (8X write speed for DVD±R) and the Mac Pro (16X write speed for DVD±R) aren’t the fastest on the market. There’s actually a mechanism created by Samsung that can write DVD±R at 20X, and it’s found in OWC’s Mercury Pro DVD-/+RW Samsung Super Writemaster 20X External DVD burner.

While 20X DVD media isn’t readily available, the Mercury Pro can burn certain 16X DVD±R media at 20X; not all 16X DVD±R media can handle the 20X speed. The Mercury Pro also adds LightScribe to the mix, a feature that allows you to etch a monochrome label onto your discs. The catch is that it can take some time to complete the etching process—up to half an hour—and you can only etch labels onto LightScribe-compatible media. According to OWC, LightScribe in the Mercury Pro works only when the drive is connected to your Mac via USB.

The Mercury Pro comes in a metallic gray plastic enclosure and features two FireWire 400 ports and a single USB port, with power provided by a small AC adapter. The enclosure employs a cooling fan that will add a slight bit of background noise to your work environment when the drive is not actually accessing a disc.

The OWC software bundle includes NTI’s Dragon Burn 4.1.6, ProSoft’s Data Backup 3.0.4, and a demo version of SmileOnMyMac’s DiscLabel 5.2.3 (the full version is $36). Informal testing using 16X DVD-R media at 20X burning delivered a seven percent speed boost over the same media burned at 16X.

Macworld’s buying advice

All told, the OWC Mercury Pro is a decent value. But while OWC throws in a starter kit of blanks (25 CD-Rs and 5 LightScribe-compatible DVDs), they only ship the demo version of SmileOnMyMac's DiscLabel 5.2.3, which you need to create the LightScribe labels. For $130, LaCie offers the d2 DVD±RW with LightScribe ( ). It’s $17 more than the OWC drive, but the d2 can also burn certain DVD±R discs at 20X and also comes with LaCie’s fully-functional LightScribe Labeler software, and, unlike the OWC drive, is able to etch LightScribe discs using either the FireWire or USB ports.

Timed trials

16x +R Burn 5:48
DL Burn 13:46
DL Copy 655MB to Hard Drive 1:32

Scale = Minutes: Seconds

How we tested: We ran all tests with the FireWire drives connected to a dual-2.66GHz Mac Pro with Mac OS X 10.5.3 installed and 1GB of RAM. We recorded the time it took each drive to burn 8GB of data onto dual-layer DVD+R media using Toast Titanium 8, and also the time it took to burn 4.4GB of data onto 16x DVD+R media. We then timed the copy of a 655MB file from a burned dual-layer DVD to the internal hard drive. —Macworld Lab Testing by James Galbraith and Jerry Jung
