While CPU, memory, OS and other variables don't often make a huge difference, there are some nonetheless. We have a computer that is used only for testing hardware. We do this so all tests can be compared reliably.
Test System:
| CPU: | AMD Athlon 64 X2 4600+ 2.4GHz | |
| Motherboard: | ASUS M2N-SLI Deluxe with BIOS 0304 | |
| Memory: | Corsair TWIN2X2048-6400 | |
| Video Card: | MSI NX7900GT-T2D256E - ForceWare v93.71 | |
| Hard Drive: | Seagate Barracuda 7200.10 SATA 3.0Gb/s 320GB | |
| Operating System: | Windows XP SP3 - NVIDIA nForce v9.16 |
For Blu-ray Disc writers, the performance tests are normally broken down into six sections: CD read, CD write, DVD read, DVD write, BD read and BD write. Each benchmark test has been run three times. The score given is an average of the three. DMA has been enabled in device manager for all IDE devices supporting it.
CD Read Tests: For the read performance section of the CD-ROM benchmarks, CD WinBench 99 v3.0 and CD Speed v4.7.7.16 are used to test read speeds, seek times and CPU usage. For DAE testing, CD Speed is used to give an overall speed rating.
CD Write Tests: To test the write speeds, Nero Burning Rom is used to write 650MB and 700MB to our test media. Times are recorded. To test rewrite scores, Nero is used again to time how long it takes to write 400MB of random files and directories. Then Roxio's Drag-to-Disc is used to test packet writing speeds. The same files are copied and pasted in Windows Explorer and timed.
DVD Read Tests: For the read performance section of the DVD benchmarks CD Speed v4.7.7.16 is used to test read speeds, seek times, and CPU usage.
DVD Write Tests: To test the DVD write speeds, Nero Burning Rom is used to write a 4.38GB image to our test media. Times are recorded. Then Roxio's Drag-to-Disc is used to test packet writing speeds. For this, 4GB of random files and directories are copied and pasted in Windows Explorer and timed.
BD Read Tests: For the read performance section of the BD benchmarks, CD Speed v4.7.7.16 is used to test read speeds, seek times, and CPU usage.
BD Write Tests: To test the BD write speeds, CD Speed's "Create Data Disc" feature is used to burn an entire BD-R/RE disc. Times are recorded.
CD Winbench 99 Scores:
| LG BP06LU10 | |
| CD Winbench 99 | 1010 KB/sec |
| Transfer Rate: Inside | 1730 KB/sec |
| Transfer Rate: Outside | 3480 KB/sec |
| Random Access Time | 160ms |
| CPU Utilization | 12.6% |
The CD Winbench test is as close as we can get to testing every day usage. It fires off eight different applications using scripts. This tries to mimic the activities of a person loading these programs onto their own computer.
LG's new portable Blu-ray Disc writer gave us some mixed performance in our CD Winbench tests. In the transfer speed tests, the drive started reading at about 11.5x on the inside of the CD and was able to reach 23.2x on the outside of the disc. While this is pretty decent for a drive with a maximum read speed of 24x, the BP06LU10's access times and overall score were not as good as some of the other portable drives we've looked at.
CD Speed v4.7.7.16 - Pressed CD:
For this test I used a pressed CD containing one Mode 1 data track. The disc is 74:38 in size and is full of data and directories.

Transfer Speed | Seek Times | CPU Usage | |||||||
| Average | Start | End | Random | 1/3 | Full | 1x | 2x | 4x | 8x | |

LG BP06LU10 |
18.10x | 10.44x | 23.87x | 176ms | 215ms | 379ms | 1% | 3% | 10% | n/a |
The BP06LU10 performed a little better in our CD Speed tests. The drive started reading at 18.10x and quickly accelerated, reaching a maximum transfer speed of 23.87x. Unfortunately, its access times were a little higher than we'd like to see.
CD Speed v4.7.7.16 - CD-R Media:
For this test I made a copy of our pressed test CD. I used 12x rated Memorex Gold 74 minute media for the tests.

Transfer Speed | Seek Times | CPU Usage | |||||||
| Average | Start | End | Random | 1/3 | Full | 1x | 2x | 4x | 8x | |

LG BP06LU10 |
18.34x | 10.53x | 24.24x | 177ms | 221ms | 400ms | 1% | 2% | 10% | n/a |
The BP06LU10 was a little faster when reading CD-R media. Thanks to this speed boost, the drive was able to reach a maximum transfer speed of 24.24x.
LG's portable Blu-ray Disc writer had no problems recognizing our 99 minute CompUSA media. The BP06LU10 read our test disc from start to finish, reaching transfer speeds near 25x before dropping down to 20.62x.
CD Speed v4.7.7.16 - CD-RW Media:
For this test I made a copy of a pressed test CD. I used some PNY 80 minute CD-RW media for the tests.

Transfer Speed | Seek Times | CPU Usage | |||||||
| Average | Start | End | Random | 1/3 | Full | 1x | 2x | 4x | 8x | |

LG BP06LU10 |
18.01x | 10.50x | 23.73x | 174ms | 210s | 384ms | 1% | 2% | 10% | n/a |
The BP06LU10 also reads CD-RW media at 24x. As you can see, the drive came very close to reaching this speed in our tests.
CD Speed v4.7.7.16 (DAE) - Pressed CD:
For this test I used Pure Funk. The CD is almost exactly 74 minutes. This helps to squeeze the maximum performance out of the CD.
Exact Audio Copy can tell us a lot about a drive's capabilities. You can see from the screen shot that the LG BP06LU10 supports accurate stream, caches audio data and has the ability to retrieve C2 error information from audio CD's.
| CD Speed | Average | Start | End | Quality | Accurate Stream |
| LG BP06LU10 | 18.12x | 10.69x | 23.96x | 10 | Yes |
For a portable drive, the BP06LU10 did fairly well in our DAE tests. The drive started out at 10.69x and reached a maximum speed of 23.96x.
CD Speed v4.7.7.16 (DAE) - CD-R Media:
For this test I used a copy of the Pure Funk CD. It's burned onto the same Memorex Gold 74 minute media I used in the CD Speed tests.
| CD Speed | Average | Start | End | Quality | Accurate Stream |
| LG BP06LU10 | 17.96x | 10.67x | 23.69x | 10 | Yes |
The BP06LU10 was a little slower when extracting audio from CD-R media. This time around, it reached a maximum DAE speed of 23.69x. So how did it do in CD Speed's advanced DAE tests? Take a look below.
LG's portable Blu-ray Disc writer completed CD Speed's advanced DAE tests with an average score of 17.07x. While the drive was able to go through the tests without creating any errors, it was unable to pass all of the on the fly copying tests. If you look at the advanced features, you can see that the BP06LU10 was able to read the CD-Text, subchannel data and lead in, but failed to read the lead out section of the CD.
