Philips JackRabbit FireWire CD-RW

2. Data Tests

Yamaha CRW70 vs Philips JackRabbit - Page 2

Data Tests

- Test Method

* SCSI Mechanic v3.0x: This was used to compare the drive's I/O performance against other various CDR-W drives (see charts). We used a pressed CD containing PlexTools v1.08 for all tests.

* Nero CD Speed v0.85 was also used to check the drive's performance with pressed CDs. For that test, we also used the PlexTools v1.08 pressed CD.

- SCSI Mechanic v3.0x results

Philips JackRabbit gave almost the same Average Random I/O result with Yamaha CRW-70 (560 kb/sec). In the sequential reading test, the Philips drive is better ,due to its increased reading speed (36x) and gave an 2855 kb/sec. The same sector read test seems to be friendlier to the Yamaha mechanism. The performance here is very high and reaches the 10750 kb/sec, while Philips gave just an 706 kb/sec average result.

- Nero CD Speed v0.85 results: (Click to see the Yamaha/Philips CD Speed Graphs)

The Philips PCRW1208JR continues to lead the race at the Nero CD Speed test. The average reading performance for Philips is 29.97X, while the Yamaha CRW70 stays back with 18.35X.

In the same test, we measured the seek time of both drives. As you can see in the graph above, the Philips drive is almost 50% faster than the Yamaha drive. The Philips drive stays below 100msec while the Yamaha drive needs almost 169msecs!

- PSX Pressed Media

For this test we used the PSX game 'NBA Jam Extreme' and we ripped the image to HD with CloneCD. We attempted to read a PSX cd title with Philips PCRW1208JR. Unfortunately, the drive was too slow and it had finished the 10% of the job in 3 hours! Yamaha CRW-70 needed 367 seconds to rip the whole CD.

- CDR Media: (Click to see the Yamaha/Philips CD Speed Graphs)

The Philips PCRW1208Jr improved its reading performance with the CDR media. The drive reaches 28.62X while the Yamaha stays behind with 18.75X.
