Review from PC Mag.com
As portable optical drives go, the Samsung SE-506AB is nearly silent. Unlike the noisy Pioneer BDR-XD04, the Samsung makes almost no noise at all, even when burning data to a disc. It also stayed cool, never getting warmer than 85 degrees Fahrenheit (as measured with a Fluke IR thermometer).
If you need some good, cheap media to use on your new drive see my post for blank media - they work out at 79 pence a disc for 25GB printable media.
The SE-506AB works with all common optical formats, including Blu-ray, DVD, and CD. With both read and record functionality, this slim drive extends its usefulness even further. Like the Pioneer BDR-XD04, the SE-506AB is compatible not only with standard single- and dual-layer Blu-ray discs, it also will read from and record to triple- and quad-layer discs.
Unlike most external optical drives, which are Windows-only, the SE506AB is also Mac (OS X) compatible, providing Blu-ray support for your iMac or MacBook Pro in addition to filling the hole left by the MacBook Air (which has no optical drive at all). One of the unique aspects of the drive is that, unlike most portable optical drives, the SE-506AB can be used with a USB-equipped TV or home theater system in addition to a standard PC. The drive is compatible with both Linux and WinCE.
Like the Pioneer BDR-XD04, the SE506AB also supports BDXL triple- and quad-layer media. Where a single layer Blu-ray disc can hold up to 25GB per disc, and dual-layer discs up to 50GB, new BDXL formats like triple-layer media holds up to 100GB, and quad-layer up to 128GB.
BDXL formats may be the next big thing in storage media, but at the moment, it's pretty rare. The few recordable BDXL discs that are on the market must be imported from Japan and sell for between $90-$100 per disc. You also will run into problems trying to play the discs on any other player, because unlike dual-layer Blu-ray discs, regular Blu-ray hardware doesn't support BDXL.
The SE506AB also comes with CyberLink 3D video software, which supports 3D playback and offers upscaling for standard definition DVDs for improved playback on high definition displays. By using the included TrueTheater 3D conversion tool, you can "transform 2D movies in 3D"—a process which adds some 3D layering to otherwise 2D images. Samsung covers the SE-506AB with a one-year warranty.
Supporting all major optical formats, the SE506AB had no problem reading any of the discs we tried, Blu-ray, DVD, or CD. The SE506AB has read support for all commercially available Blu-ray formats, including BD-ROM, BD-R and BD-RE in dual-, triple-, and quad-layer formats. Read speeds vary between 4x for triple-layer BD-RE discs and 6x for standard BD-ROM. All formats of DVD and CD are supported, including odd shaped discs, such as DVD business cards. DVD media reads at 8x, while CD media reads at 24x. These speeds are identical to those offered by Pioneer's BDR-XD04.
Equally broad support is available for for writable media, supporting all formats of BD-R and BD-RE, including dual-, triple-, and quad-layer discs. Write speeds range between single- and dual-layer BD-R (6x), triple- and quad-layer BD-R (4x), and all BD-RE formats (2x). Writing support includes DVD+R and DVD-R (8x), single and dual-layer DVD+/-RW (6x), and both CD-R and CD-RW (both at 24x). It gave us no problems in testing, and the included CyberLink software is straightforward and easy to use.
The Samsung SE-506AB External Slim Blu-ray Re-Writer offers all of the usefulness and portability of the Pioneer BDR-XD04, with the added benefit of being quiet and staying cool. It's a little bigger and a little heavier, but with the SE-506AB's AV connectivity and built-in 2D to 3D conversion (not to mention cheaper price), a few ounces are easy to overlook. The Samsung SE-506AB External Slim Blu-ray Re-Writer snags our Editors' Choice for portable optical drives.
