CD/DVD Performance Tests
Nero Burning ROM Ultra 6

Ahead software, the makers of Nero Burning ROM, have an excellent selection of free utilities to test the functions of various types of optical drives.  Each of these small applications perform a number of specific tasks that show us what each drive is capable of.  In this next section we ran several of these tests on the AOpen DRW4410 and included the results of the Teac DV-W50D drive for comparison.  Please note that in each test, the Green line represents Transfer Rates while the Yellow Line represents Rotation Speed.

Nero CD-DVD Speed - CD Data Test:

In our first run of Nero CD-DVD Speed we'll focus our efforts on standard CD-ROM performance.  With this benchmark, we loaded a 703MB CD-R in the drive and let CD-DVD Speed run through its cycle of tests.

The Teac drive was consistently slower with reading of standard CD-Rs, from start to finish, which was no real surprise with its 32X rating vs. the AOpen's 40X.  The DRW4410 started around 18X (similar to what Nero had reported) and went directly on up to 40X, with an average speed of 30.94X.  The DV-W50D followed the same pattern, from 15X to 33X, with an average speed of 25.33X.  Seek times were lower on the DRW4410 than they were on the DV-50WD, and were well within the specs (<120ms random stroke).  CPU utilization, however, was much higher at all speeds when using the DRW4410.

Nero CD-DVD Speed - CD Audio Test:

To test each drive's audio extraction performance, we placed in an audio CD by Shania Twain.  The CD ran over 73 minutes, and although the test runs similar to the CD data test, it also measures how well the drive can extract audio tracks.  In order to do this, audio sectors are extracted to the hard drive at three different locations on the CD.  The same sectors are read again and compared to the sectors written to the hard drive.  Depending on the number of differences, the DAE quality will be rated from 0 to 10, with 10 being a perfect score.

Using a pressed Audio CD, the performance of the AOpen drive dropped slightly, maxing out at 38.11X, and averaging a speed of 29.04X.  It should be noted, however, that the Teac drive dropped by the same amount as well.  On the brighter side, DAE quality was rated as a 10, meaning no differences were reported between the actual tracks and those extracted to the hard drive.  Nero also reported that the AOpen DRW4410 supports accurate data streaming.

Nero CD-DVD Speed - DVD Data Test:

In the next two tests we focused on the drive's DVD reading performance.  Each drive is configured to perform differently based on whether a DVD movie or DVD data disk is inserted in the drive.  We started by placing in a DVD+R containing over 4GB of AVI files.

The AOpen drive started at 4X, and remained there the entire time of the test.  The rotation speed continually slowed down as we reached the end of the test.  These results were the complete opposite of what we saw with the Teac, where the rotation speed held steady as the transfer rate went from 2.5X all the way up to 6X.  The Teac DV-W50D also had much better seek times at random and 1/3 stroke, although this flip-flopped with the DRW4410 at full stroke.  We were disappointed by the random access time that we recorded with the DRW4410, which were well above the listed 140ms in the drive's specs. 

Nero CD-DVD Speed - DVD Movie Playback Test:

In the final Nero CD-DVD Speed test we wanted to check the performance with a double-layered movie DVD.  We inserted a copy of Daredevil, grabbed a snack, and clicked on the Start button to get the results.

Teac DV-W50D

Each drive uses it's own method for DVD playback; AOpen uses a P-CAV (Partial - Constant Angular Velocity) strategy and Teac CLV (Constant Linear Velocity).  In P-CAV, the drive starts off in CAV mode (at the highest possible RPM) then moves over to CLV mode when the maximum data rate is reached.  CLV is an older method in which the data rate remains constant while the rotation speed decreases.  It's generally accepted that CAV solutions may be quicker than CLV, but at a slight cost of quality and/or accuracy.  Both drives are remarkably similar, however, in the seek times and CPU utilization.
