Sony BWU-200S detail information

Writing technique     

Now it’s time to take a closer look at the write technology used by the Sony BWU-200S:

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 Sony BWU-200S, it should be able to write CD-R media at a maximum speed of 40X on supported media.

The Sony BWU-200S used Z-CLV, (Zone-Constant Linear Velocity), to write at its maximum speed of 40X.  This gives an average speed of 30.45X with a total write time of 3 minutes and 12 seconds.

For comparison we have made the following table: 

The Sony BWU-200S is a fast performer when comparing write times.

CD-Rewritable

The Sony BWU-200S uses Z-CLV (Zone-Constant Linear Velocity) to write CD-RW media at its maximum speed of 24x, with an average write speed of 23.09x and writing time of 3 minutes 35 seconds.

For comparison we have made the following table: 

The Sony BWU-200S is the fastest of our test drives at writing CD-RW.

16x DVD+R

The Sony BWU-200S should be able to write DVD+R media at a maximum speed of 16X.

The Sony BWU-200S uses CAV (Constant Angular Velocity) to write DVD+R at the maximum supported speed of 16x. This results in an average write speed of 11.21x and a writing time of just 5 minutes and 55 seconds.

Here we have prepared a table to show how the Sony BWU-200S compares with other Blu-ray drives:

The BWU-200S, being 16X capable, is right in the mix of things when we look at overall write times.

16x DVD-R

The Sony BWU-200S should be able to write DVD-R media at a maximum speed of 16X.

The Sony BWU-200S uses CAV (Constant  Angular Velocity) to write DVD-R at the maximum supported speed of 16x. This results in an average write speed of 11.21X and a writing time of just 6 minutes and 03 seconds.

Here we have prepared a table to show how the Sony BWU-200S compares with other Blu-ray drives:

As you can see the Sony BWU-200S being 16X capable along with only one other Blu-ray drive tested; and it performs nicely.

8x DVD+RW

According to the specification of the Sony BWU-200S it should be able to write to DVD+RW at a maximum of 8X.

The Sony BWU-200S uses Z-CLV (Zone-Constant Linear Velocity) to write DVD+RW at 8x. The average speed is 6.79x and total writing time is 9 minutes and 25 seconds.

For comparison we have made the following table: 

The Sony BWU-200S performs on average with other 8X capable drives.

6x DVD-RW

According to the specification of the Sony BWU-200S it should be able to write to DVD-RW at a maximum of 6X.

The Sony BWU-200S uses CLV (Constant Linear Velocity) to write DVD-RW at 6x. The average speed is 5.83x and total writing time is 10 minutes and 31 seconds.

For comparison we have made the following table: 

As you can see, the Sony BWU-200S performs on average when compared with the other drives we have tested.

Let’s take a look at DVD±R DL writing techniques……

8x DVD+R DL 

According to the specifications of the Sony BWU-200S, it should be able to write DVD+R DL at a maximum speed of 8X.  Here are our results.

The Sony BWU-200S uses P-CAV, (Partial-Constant Angular Velocity), to write at its maximum speed of 8X. This gives an average speed of 6.73X and a total writing time of 16 minutes and 51 seconds.

8x DVD-R DL

According to the specifications of the Sony BWU-200S, it should be able to write DVD-R DL at a maximum speed of 8X.  We regret that at this time we do not have any 8X capable media.  Below you will see our test using a 4X DVD-R DL disc.

The Sony BWU-200S uses CLV, (Constant Linear Velocity), to write at 4X with this media with an average speed of 3.91X and a total write time of 27 minutes and 51 seconds.

For comparison we have made the following table:

The Sony BWU-200S was the fastest among our other tested drives for DVD+R DL; and the slower writing to DVD-R DL is due to the review team not having additional –R DL media to test with at this time.

DVD-RAM  

The specifications for the Sony BWU-200S 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 Sony BWU-200S uses CLV (Constant Linear Velocity), to write at is maximum speed of 5X.  This gives an average speed of 4.91X and a total writing time of 11 minutes and 49 seconds.

Summary

The Sony BWU-200S performed well with our writing tests.  We regret that we do not have any DVD-R DL capable of writing at the drives rated speed to test with at this time. Let’s move on ahead and check out the reading performance on the next page…..
