Customer Reviews

Products are good until they break, at which point I wish you luck getting them fixed.

I burn data to DVD or Blu-Ray using the excellent free ImgBurn (and write at 12x speed to this ASUS BD writer).
Very fast and quite, works very well, it is an awesome product and very great purchase.

I ran one experiment to confirm that USB 3.0 really is about 2.5x faster (as some web sites claim) to burn Blu-ray Discs (BD-R) than USB 2.0 (ie. the USB channel is the bottleneck, not the disk or cpu speed). Using an ASUS laptop with an i7 cpu, a USB 3.0 port and 4GB memory, I backed up 22.3 GB of data (5,339 files) to a BD-R at 12x maximum write speed using the included ASUS/Cyberlink Media Suite program Power2Go 7. It took 01:00 minute for Power2Go to "prepare" the data for writing (these times are not rounded off, though they coincidentally look like they are).

Actual write time to write 22.3GB to BD-R(SL) at 12x:
-- USB 3.0 : 11:00 minutes -- 2.0 GB/min or 120 GB/hr
-- USB 2.0 : 30:30 minutes -- 0.73 GB/min or 44 GB/hr
For this experiment, USB 3.0 wrote data 2.7x faster than USB 2.0.

For another experiment, the measured write speed for a BD-R(DL) disc was 90 GB/hr (38.0GB at 8x).

Using this BD writer, so far I have written 7 BD-R(DL) disks at the max 8x and 4 BD-R disks at the max 12x speed without any problems, even though BD-R(SL/DL) Verbatim media is only rated for 6x speed. I also confirmed the 16x write speed to DVD+R media.

Currently Verbatim 25GB BD-R discs cost about $2/disc (getting close to the price per GB of DVD discs!) and 50GB discs are about $7/disc. Prices will continue to fall.

Summary of hardware:
-- this Blu-Ray Writer (Burner) is among the fastest available at this time
-- USB 3.

Very good performance and easy installation. Looks sleek with its glossy black enclosure. USB 3.0 is a clear advantage for blu-ray disk burning. However, some enclosure design aspects detract from ease of use.

Bought this to use with a Lenovo W520 laptop workstation running Windows 7.0 Pro. I do HD video encoding and need a reliable external blu-ray burner with USB 3.0 for video disk production. For years I used non blu-ray LG burners with excellent results. LG's blu-ray burner is still USB 2.0 or I might have considered it.

This burner has a power adapter and USB 3.0 port on the back along with a power switch. It's packaged with a USB 3.0 cable, power adapter, and useful but limited set of Cyberlink software. Cyberlink offers a discount upgrade to their full software suite. I find the provided Cyberlink software right for my needs.

Installation was easy. My laptop recognized both the burner and its USB 3.0 connection. Cyberlink software installed without issue. Blank blu-ray DVD disks are more expensive than regular blank DVDs so disk burn reliability is a high priority. I've burned twenty blu-ray video DVDs using ProShow Producer and other video encoding software. All disks were produced quickly without errors. These work perfectly in both Sony and Sharp Blu-ray players.

There are three enclosure design aspects I don't like. They don't affect disk burning performance and are clearly subjective. First, the top of the player is not flat so I can't stack two of these like I do my bricklike LG burners. Second, the triangular blue LED light on top is very bright and distracting. I can tape over it but I'd prefer it be switchable.

I purchased this due to the combination of great price, USB 3.0, and 12X burning support, which is apparently hard to find with an external drive. The ASUS name was a selling point as well, as I've used ASUS motherboards and other products for years. That and free shipping with Amazon Prime. The drive arrived within the 2-day window, as expected with Amazon Prime. (well worth it in my opinion)

I was pleased with the design and performance of the drive. You can use it vertically with the included base, which fits securely, or horizontally without the base. The included power supply is compact and has a nice long cord. A USB 3.0 cable is included. The sliding power switch on the back of the drive is a nice touch, though it could be implemented a little better. I backed up most of my system to BD-R the same night I got it using a freeware utility I like, called "Imgburn" The drive flawlessly wrote each disc at the maximum speed available for the type of discs I bought. Everything verified successfully.

I would have given this 5 stars if the included software wasn't so poor. Naturally with your expensive purchase a full version of the software isn't included either. I declined installing the full 'suite' that came with it, as I don't like a lot of useless bloat on my PC, choosing only to install the "PowerDVD" software for playing BD discs. Pitifully, Windows 7 doesn't have native support for playing BD discs without jumping through hoops. Pretty much history repeating itself in the same fashion as when standard DVDs became the rage and Windows wouldn't play those either.
