Data Tests
Test Method:
- SCSI Mechanic v3.0: This was used to compare the various DVD-ROM's
I/O performance (see charts). We used a pressed CD containing PlexTools
v1.08 for all of the tests.
- Nero CD Speed v0.83 beta was also used to check the drive performance
with pressed CDs. For that test we used PlexTools v1.08 original CD.
- SCSI Mechanic v3.0 results:
The LiteOn LTD163 seems to be the fastest drive among our 3 contestants.
The drive managed to give an "Average Sequential I/O throughput"
of 5393kb/s, while the AOpen 1648 came second (5267Kb/s) and the Matsushita
was last with 5211Kb/s. The Matsushita had a superb performance in the "Average
Same Sector I/O throughput test" and came second in the "Average
Random I/O" test. LiteOn has the worst "Average Random I/O"
and "Average Same Sector I/O" tests.
- Nero CD Speed 99 v0.83 results:
Using Nero CD Speed 0.83, we confirmed our previous test. The LiteOn LTD163
is the fastest drive, the AOpen 1648 comes second and Matsushita third, but
by a very narrow performance gap (0.01X).
In the Seek Times test, the Matsushita SR-8586 earned the best overall results
with a seek time of under 80ms. The LiteOn comes second in the random test,
but finishes last in the 1/3 and full stroke test. The AOpen 1648 seems to
perform steadily and very close to Matsushita SR-8586.
- PSX Pressed Media
In order to fulfill a request made by some of our frequent visitors, we
have included a test with mixed mode CDs (mainly PSX). For these test we used
the PSX game 'NBA Jam Extreme' and we ripped the image to HD with CloneCD.
We measured the reading times and we can say for sure that the Matsushita
SR-8586 simply rocks the competition...The LiteOn drive needs 5:15mins, while
the Matsushita SR-8586 needs only 1:31mins, and the AOpen 2:59mins:
- CDR Media
The LiteOn LTD163 proves its superiority with CDR media. The interesting thing
about this is that the Matsushita SR-8586 gets the second place now, since the
AOpen drive kept slowing down by the end of the disc.
