How We Tested

There are lots of ways that you can test computer components, but here at TrustedReviews we feel that the best way to test a product is to perform real world tasks. To this end we devised a set of tests that reflect what the drives will actually be used for. All the drives were tested using the supplied writing software.

Large File Test

We used a 4.3GB MPEG-2 file to test how quickly each drive could write a single large file. This test was performed using DVD-R, DVD-RW, DVD+R and DVD+RW media.

Mixed Files Test

To simulate a mass file copy or backup we used a 4.5GB batch of files. This is one of the most common tasks that these drives will be faced with. The 4.5GB mixed files test was performed using DVD-R, DVD-RW, DVD+R and DVD+RW media.

Formatting Tests

Using re-writable media involves formatting the discs occasionally to clear off old data. We performed a full disc erase on all supported re-writable media and timed the result. This test was performed using DVD-RW, DVD+RW and CD-RW media.

MP3 File Copy

To simulate the CD burning duties likely to be facing these drives we copied 600MB of MP3 data to both CD-R and CD-RW media.

All these tests were timed and the results are shown on the graphs on the following pages measured in minutes and seconds.

Finally a thank you must be given to TDK who supplied us with all the media used for this test. When testing optical drives it’s vitally important that high-quality media is used to get the best out of the units.
