Sony CRX175A CD-RW

2. Data Tests


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 v0.84b 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

In the average random I/O test, Sony CRX175A gave an 610 kb/sec performance and did not manage to stay close enough to how the other drives performed. The sequential test results were better for Sony since it gets the second place behind the Plextor drive.

- Nero CD Speed v0.84 results: (Click to see the CD Speed Graph)

In the Nero CD Speed results the Sony drive gave exactly the same performance as Yamaha CRW3200E! The drive gave the second best reading speed with 30.56x.

In the same test, we write down the seek time of Sony CRX175A in random, 1/3 and full disc access. The drive had a good performance with 116sec in the Random test. Yamaha and Teac offer a different approach, since they hold the lead in the seek time issue with 84 msec and 77 msec respectively.

- PSX Pressed Media

For this test we used the PSX game 'NBA Jam Extreme' and we ripped the image to HD with CloneCD. We measured the reading time of the SONY CRX175A , which is one of the best with 57secs.

- CDR Media: (Click to see the CD Speed graph)

As in the pressed cdr reading test, Sony managed to give a good 31.2x performance, and shares the second place with the Yamaha drive.
