16x/48x DVD Round-up - Page 2

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.
