Performance

CD WinBench 99

CD WinBench 99 is the first of my list of tests.

Although the junior model was reading the inner tracks of the disc at a smaller speed than the GO-0804A, it scored more points, mostly due to its smaller disc access time (the difference in this parameter amounts to 12 milliseconds is quite big). Besides that, the GO-0404A turns to be faster than the other drive when reading the external tracks. The higher access time of the GO-0804A must have been due to its using another OPU, and this affected the results of the test considerably.

CD-R Burning

Verbatim Datalife 52x blanks were used for this test.

The drives both took about the same time to burn discs at these three speeds. The maximum gap (for 40x and 24x speeds) doesn’t exceed 7 seconds. I guess this is negligible considering the total times. So, the drives match each other in this test, but it’s quite natural. Generally speaking, you can only see any significant difference between two optical drives of the same speed formula when the real speed doesn’t coincide with the specified one, but it’s not the case here as both models fully comply with their own specs.

Now let’s see the devices read a CD-R disc written at the maximum speed:

It’s all right with the senior model – the graph is smooth and clear, indicating a good burn quality. The graph of the junior model is somewhat strange. Well, there are no speed slumps or failures here, but the read algorithm is identified as Z-CLV, although it is clearly pure CAV. This confusion can be observed in other utilities, not only in CD/DVD Speed, and you’ll see later on that this is not the only peculiarity of the GO-0404A. Just now I can only say that the drives are both good at reading CD-Rs.

The results of CD WinBench 99 are confirmed here. The junior model sports a slightly higher average read speed and a considerably smaller access time (the difference is 21 rather than 12 milliseconds as in WinBench). It also has a perceptibly higher burst rate. So, in spite of the same speed formula the GO-0404A turns to be faster in practice than the senior model. As for ergonomics, both drives have the same full disc recognition time, 13 seconds. This is a good result: better than the Plextor had, but worse than the Sony’s record of 8 seconds.
