Nero CD Speed 99 - Audio - Benchmarks Source: Ahead Software

CD Speed is a CD-ROM benchmark which can test the most important features of a CD-ROM drive. In this particular test we use a pressed Audio CD with about 65 minutes of audio on it as the test disk. CDROM's in general have a harder time processing audio data, and hence the results can be drastically slower than that of data tests alone.

Audio disk benchmarks peg the Plextor PXW4012TA in a fairly unflattering position - average speeds drop down to 8X - making it one of the slowest on this test platform. These results may not be 100% accurate as you'll notice the CPU usage jumps up to 69% at 8X speeds. Seek times are also slower over the mean average of the other drives we have tested.

Sandra shoots out some good Drive Index results for the PXW4012TA drive, but access times are pretty slow here; 238ms is more than twice that of the next drive but notice that Buffered Read (23MB/s) is very, very large. The next comparable Buffered Read would be from the DD-500M at just 19MB/s.

Nero CD Speed 99 - Burn Test - Benchmarks Source: Ahead Software

Nero's CD Speed burn tests are done twice, once with a CDR rated to 1x-24x burn speed, and a CD-RW rated to 4x-10x. Each disk was test with files of about 640MB in size. This test is done by simply placing blank recording media into the burner and running CD Speed 99; the software will detect if it is CD-R or CD-R/W media and run the appropriate tests.

The Plextor PXW4012TA optical drive is rated at 40X for CD-R's and in our tests the drive did top out at that speed. Average speeds reigned in at a more modest 30.59X across the disk, which is still very good. The CDRW media test capped out at 12X which is consistent with the drives rating.

Obviously, as a burner the Plextor PXW4012TA meets its listed specs which is something we always like to see. While average CDR burn rates are never at the maximum speed for the entire disk, the Plextor PXW4012TA does manage to pull its weight.
