The Lite-On EZ-Dub is by far the best optical burner I have ever used. Often times tower computers are placed under desks or tucked out of the way, which can hamper access to internal drives. If you have the space, an external drive can be placed in a more accessible location, such as on your desktop, where it is easier to use. Being external also makes it highly portable, and the USB 2.0 interface is compatible with nearly every modern computer system. The connections are simple, requiring only power and USB to work, and the touch sensitive Dub and File selections are also within easy reach, even when using the included stand to hold the unit on its side.
The software bundle is excellent; many users will already be familiar with Nero so there shouldn't be much of a learning curve. And the EZ-Dub software is so simple to use even a child could be making copies within a matter of minutes. The burning may take a little longer than an internal drive, due to the USB interface bandwidth limitation, but if anything, the regulated speed should reduce the chances of burning coasters. The drive is extremely quiet; I was surprised at how little noise it makes, whether spinning the disk at full speed or even just opening or closing the tray.
I found the Lite-On EZ-Dub drive online for around $50-$60 which as usual is near the bottom of the price range for external burners. The only thing that I found the EZ-Dub does not seem to offer is Lightscribe, which I found strange since their other external drives without the EZ-Dub do support it. I'm not sure how long until some manufacturer comes out with an eSATA external burner, but that would definitely be on my wish list as well if I were in the market for one. But given the price, ease of use and quiet operation of the drive, the Lite-On EZ-Dub External Writer easily earns the OCIA.net Seal of Approval.
