LG BP40NS20 Portable Blu-Ray burner review

Reading performance

---

For these tests we will once again use Nero DiscSpeed, and Opti Drive Control to read various CDs and DVDs, including audio discs and DVD-media. As already mentioned in the introduction, this drive supports:

• BD-ROM 6x
• DVD-ROM 8x
• CD-ROM 24x

Pressed discs:

For this test we used a pressed CD-ROM disc, containing various software, that is slightly over 75 minutes in length. Below you will see the result produced:

The LG BP40NS reached its max speed without any issues.

CD Recordable discs:

For this test we made a copy of the original CD. The disc we used was an unbranded 52x certified CD-R disc manufactured by Plasmon.

Again the drive is able to reach a read speed of 23.95x.

CD Re-writable discs:

Again, we made a copy of the original CD, this time we used a Verbatim 4x CD-RW disc (thanks to Verbatim for providing me with this media).

The LG BP40NS20 reached 24.16x read speed.

Audio – Digital Audio Extraction:

To test the digital audio extraction performance of the LG BP40NS20, again we used Optic Drive Control to measure the transfer rate. The audio disc was 76 minutes in length (75:56:45).

The LG BP40NS20 is unfortunately a slow drive when it comes to reading audio.

DVD reading performance:

---

Again, we will use Opti Drive Control to measure the reading performance, this time for various types of DVD discs. The drive should read pressed single and double layer DVD discs at 8x.

Pressed DVD Video:

For our DVD reading performance tests we are going to start with Single and Double Layered DVD video discs. Whilst only single speed is required to watch DVD movies, it’s useful to be able to read the discs at higher speeds if you’re going to extract (rip) the contents of the disc to your hard drive.

DVD Video (single layer)

DVD Video (double layer OTP)

The LG BP40NS20 had no issues reaching its max speed of 8x.

DVD – DVD+R/RW:

For this test we used a Verbatim 16x DVD+R and a Verbatim 8x DVD+RW with about 4.4GB of data. Below are the results:

The drive was able to reach a max speed of 6x but the speed dropped on the second layer. It took 47 minutes and 7 seconds to finish.

BD-R SL:

On this test the LG BP40NS20 reached the max speed of 6.04x. It took 20 minutes and 47 seconds to finish.

BD-R LTH:

The LG BP40NS20 can read back LTH media at 6x. It took 21 minutes and 7 seconds to finish reading our test media at a max speed of 5.07x.

BD-RE SL:

Again the LG BP40NS20 shows a great performance, it was able to reach 60.3x read speed, and it took 20 minutes and 51 seconds to finish the task.

The LG BP40NS20 has shown itself to be an excellent and reliable reader.
