Disc Writing Technology

Writing Technique

Now let’s take a closer look at the writing technology of the LG BH08LS20.

For these tests we used CD-Speed and wrote a full disc at the drives maximum speed.

CD-Recordable:

According to the specifications of the LG BH08LS20, it should be able to write CD-R media at a maximum speed of 48X on supported media.

The LG BH08LS20 uses P-CAV, (Constant Angular Velocity), to write at its maximum speed of 48X, this gives an average speed of 36.57X.

For comparison we have made the following table: 

As we can see from our chart the LG BH08LS20 was the fastest (time wise) at writing our test CD-R media.

CD-Rewritable: 

The LG BH08LS20 uses Z-CAV 2-Zone (Zone-Constant Linear Velocity) to write CD-RW media at its maximum speed of 24X, this gives an average speed of 23.40X.

For comparison we have made the following table:

As you can see from the graph, our LG BH08LS20 is among the fastest at CD-RW writing, with a time of 3 minutes and 46 seconds.

16X DVD+R

The LG BH08LS20 should be able to write DVD+R media at a maximum speed of 16X.

The LG BH08LS20 uses CAV, (Constant Angular Velocity) to write DVD+R at the maximum supported speed of 16X. This gives an average write speed of 11.91X and a writing time of 5 minutes 46 seconds.

For comparison we have made the following table:

As you can see from the graph, our LG BH08LS20 is one of the fastest at DVD+R writing, with a time of 5 minutes and 46 seconds.

16X DVD-R

The LG BH08LS20 should be able to write DVD-R media at a maximum speed of 16X.

The LG BH08LS20 uses CAV, (Constant Angular Velocity) to write DVD-R at the maximum supported speed of 16X. This gives an average write speed of 11.91X and a writing time of 5 minutes 41 seconds.

Here we have prepared a table to show how the LG BH08LS20 compares with other Blu-ray drives:

As you can see from the graph, our LG BH08LS20 is a fast burner with our DVD-R writing, with a time of 5 minutes and 41 seconds.

8X DVD+RW

The LG BH08LS20 uses Z-CLV (Zone-Constant Linear Velocity) to write DVD+RW at 8X. The average speed is 7.85X and total writing time is 7:18 minutes.

For comparison we have made the following table:

 As you can see from our graph the LG BH08LS20 was among the fastet when writing to our test DVD+RW, with a time of 7 minutes and 18 seconds.

6X DVD-RW

The LG BH08LS20 uses CLV (Constant Linear Velocity) to write DVD-RW at 6X. The average speed is 6.03X and total writing time is 10:04 minutes.

For comparison we have made the following table: 

As you can see from our graph the LG BH08LS20 was at the top of the competition writing DVD-RW, with a time of 10 minutes and 04 seconds.

4X DVD+R DL

The LG BH08LS20 supports 4X writing speed on DVD+R DL media.

The LG BH08LS20 uses CLV (Constant Linear Velocity) to write DVD+R DL media at 4X which gives an average write speed of 3.95X and a total write time of 27 minutes and 23 seconds.

4X DVD-R DL

The LG BH08LS20 supports 4X writing speed on DVD-R DL media. 

The LG BH08LS20 uses CLV, (Constant Linear Velocity) to write DVD-R DL media at 4X. The average speed is 3.94X and the total writing time is 27 minutes and 57 seconds.

For comparison we have made the following table:

As you can see from our chart above the LG BH08LS20 posts very competitive times when we compare it at 4X writing on both DVD+DL media.

DVD-RAM

The specifications for the LG BH08LS20 state that the drive is capable of writing DVD-RAM at 5X.  Let’s take a look at the write strategy for this media.

5X DVD-RAM Writing

The LG BH08LS20 uses P-CAV (Partial Constant Angular Velocity), to write at is maximum speed of 5X.  This gives an average speed of 4.57X and a total writing time of 12 minutes and 21 seconds.

Summary

The LG BH08LS20 performed well with our writing tests and, able to meet or exceed the published specifications in regards to writing speeds.
