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, 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 WH10LS30 could read them back. .

The WH10LS30 is the first drive from LG that can write to BD-R media at 10x. By looking at the screenshot above, you can see that LG's new drive starts writing at about 5.1x and accelerates, reaching its maximum speed at the 14.25 GB mark.

| BD-RE | 39:50 | 45:20 | 45:07 | 39:21 |
| BD-R DL | 27:08 | 25:06 | 30:08 | 31:32 |
The WH10LS30 performed very well when writing to BD-R media. While not as fast as the Plextor PX-B940SA, it took about 11 and a half minutes to burn a 25GB disc. LG's new drive didn't disappoint when writing to BD-R DL media either. Thanks to its 8x writing speed, the WH10LS30 took a little more than 27 minutes to burn an entire 50GB worth of data.

The WH10LS30 completed our Blu-ray writing tests without any problems. The drive wrote to all of our test media at its rated speeds or better and, looking at the transfer rates, you can see that it had no problems reading the discs back.
Performance Revisited:
Like LG's previous Super Multi Blue drives, the WH10LS30 performed pretty well throughout most 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 WH10LS30 either. The drive was able to read BD-R discs at 10x and both BD-RE and BD-R DL media at 8x, but slowed to 4.8x when reading AACS protected BD-ROM's.
The WH10LS30 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 at 48x and single layer data DVD's and DVD±R media at 16x. When it came to writing CD's and DVD's, the WH10LS30 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 WH10LS30 gets a solid 8 out of 10 for the performance section of this review.
