- Processor: Intel i7 750
- RAM: 4 GB Corsair dual channel kit DDR3
- GFX: ATI HD 5670 (512 Megabytes GDDR5 HDCP compliant)
- Hard disk OS: Western Digital Black 1Tb
- PSU: Chieftec 500W
- Display: FujitsuSiemens 22”
- Operating System: Windows 7 Professional (64 bit)
System setup:
The LG BH12LS35 was connected to one of the main-board’s SATA ports and reports as a HL-DT-ST BD-RE BH12LS35 Device.
From the screenshot from Nero InfoTool above, we can see the LG BH12LS35 supports burning of BD-R, BD-R DL, BD-RE, BD-RE DL and BD-ROM –R/RE DL reading. The drive came shipped with firmware version 1.00 and no updates were available at the time of writing this review.
Installed software:
Features and techniques
Software Bundle:
Now let’s take a brief look at the supplied software bundle. Please note that we may not use any of this software in this review.
The Super Multi Blue Install Disc (for windows) the LG BH12LS35 has the following software:
- CyberLink BD Advisor
- CyberLink LabelPrint
- CyberLink MediaShow
- LG Burning tool
- CyberLink PowerBackup
- CyberLink PowerDVD 9
- CyberLink PowerProducer

BookType (BitSetting):
The LG BH12LS35 can only set BitSetting manually, and is capable of writing DVD+R and +R DL media with the DVD-ROM book type, but after a reboot the setting goes back to +R/R DL.
Here is how you could check if your discs are really written with DVD-ROM book type:
Start Opti Drive Control and click the Disc info button and you should get something like this:
DVD+R with book type DVD-ROM
Another quick test is to start Nero CD-Speed and look at the disc information:
Writing technique
Now it’s time to take a closer look at the writing technology used by the LG BH12LS35.
For these tests we used Opti Drive Control, and wrote a full disc at the drive’s maximum speed.
CD Recordable:
According to the specifications of the LG BH12LS35 it should be able to write CD-R media at a maximum speed of 48x.
The LG BH12LS35 uses CAV, (Constant Angular Velocity), to write at its maximum speed of 48X. This gives an average speed of 34.51x and a total writing time of 2 minutes and 40 seconds.
For comparison we have made the following table:
