BD Write and ReWrite Tests - Nero CD Speed v4.7.7.16:
To test the BD writing performance of LG's new drive I used BD-R, BD-R DL and BD-RE media from Memorex, Moser Baer, Panasonic, Ritek, Sony, TDK and Verbatim. To get the writing times, CD Speed's "Create Data Disc" feature was used. I also ran the discs through CD Speed's transfer rate test to make sure that the BH08LS20 could read them back. .

The BH08LS20 is the first drive from LG that can write to both BD-R and BD-R DL media at 8x. When writing to 25GB BD-R discs at this speed, the drive starts at 4.5x and quickly accelerates, reaching 8x at the 11GB mark. Looking at the other screenshot, you can see that the BH08LS20 isn't nearly as aggressive when writing to 50GB BD-R DL media. This time around, the drive starts writing at 3.5x and doesn't reach 8x until the 22.5GB mark.

The BH08LS20 performed very well when writing to BD-R media. It completed our tests in record time, beating the BWU-300S by a small margin. LG's new drive didn't disappoint when writing to BD-R DL media either. Thanks to its 8x writing speed, the BH08LS20 took 31 and a half minutes to burn an entire BD-R DL disc.

The BH08LS20 completed our Blu-ray writing tests without any problems. Amazingly enough, the drive wrote to all 25GB and 50GB BD-R media at 8x, including Verbatim's 2x BD-R discs.
Performance Revisited:
Like LG's previous Super Multi Blue drives, the BH08LS20 performed pretty well throughout most of our tests. The drive flew through our BD writing tests, turning in some very impressive times with BD-R and BD-R DL media. Reading Blu-ray Discs wasn't a problem for the BH08LS20 either. The drive was able to read BD-R and BD-R DL media at 8x, but slowed to only 4.8x when reading AACS protected BD-ROM's and BD-RE discs.
The BH08LS20 also did reasonably well in our CD and DVD read tests. Along with some fairly good seek times, the drive read CD's at speeds as high as 48x and single layer data DVD's and DVD±R media at 16x. When it came to writing CD's and DVD's, the BH08LS20 held its own throughout most of our tests and the writing quality was, for the most part, quite good. With all things considered, the LG BH08LS20 gets a solid 8 out of 10 for the performance section of this review.
