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 CD-ROM with about 640MB of data as the test disk. Using a CDR or CDRW as
the test disk may (or may not) impact the results slightly, so the pressed disk
is the de facto standard.

During the CD-Speed data transfer tests, the CPU usage remained the lowest of all the reference drives, 3% at
maximum. Average disk speeds (32X)were placed at second highest, right after those of the 52X Samsung CD-ROM. The drive
appears to have peaked at about 50X which means that it is capable of
producing quite healthy speeds. Interestingly, the Pioneer drive had the fastest disk recognition times of all,
the slowest disk load times... essentially evening things out between disk insertion
and disk boot up.
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 benchmarks usually see higher CPU usage results and lower disk speeds. In this set
of tests, the Pioneer DVD-500M produced very fast disk access times (29X) and very
low CPU usage results (just 4% at max). Access times between the DVD-500M and
the Samsung SC-152/SW-224 were pretty much the same.

Sandra is designed
to test the theoretical power of a complete system and individual components.
The numbers taken though are again, purely theoretical and may not represent
real world performance. Unfortunately we do not have the test results
from the SW-216 to include in this comparison because an older version of Sandra
was originally used to test it.

Sandra doesn't have much
good to say about the DVD-500M in this test - giving it the lowest drive index
of the three. A Drive Index of just 1282 is not much to write
home about, but we were glad to see that buffered read rates lived
up to their listed values (21MB/s) by coming in at
19MB/s.
Conclusions: Pioneer are like Sony when it comes to optical drives,
many of us just assume they produce good sold drives because that is what we have heard. In this case the 16X DVD-500M from Pioneer lives up to expectations, providing a quick platform to view DVD's from. Retailing for about $55USD, the drive is a good value and one that we had no problems with while playing back entire DVD's like the Matrix.
