Data CD Tests

- Pressed CD results

(74min and 80min CDSpeed graphs )

Mitsumi CR-48XFTE showed a very unstable behavior when it came to reading pressed or CD-R discs. The drive even read the disc (CAV) without reaching the maximum 54x speed (see the 74min CDSpeed graph), or it lowered the reading speed by the end of the disc. However, we managed to get the results illustrated in the chart by using an 80min CD-R disc. In this case, the Mitsumi CR-48XFTE performed very well and reached the 55.12x in the outer tracks of the CD, resulting to an impressive average speed of 41.48x.

Mitsumi CR-48XFTE gave some of the best seek times we have ever experienced from a CDRW drive. The drive gave a 58msec result for the Random stroke, 69msec for the 1/3 and 183msec for the Full seek test.

- CDR Media results

(74min and 80min CDSpeed graphs)

As in the case of pressed media, Mitsumi CR-48XFTE lowered the reading speed by the end of the disc, as you can see on the 80min CDSpeed graph link above. The drive finished reading at an average speed of 37.45x. However, reading of the 74min test disc offered better results, with the drive being able to reach the 53.4x maximum speed.

Again, Mitsumi CR-48XFTE offered very low seek times, as low as 118msec for the case of full seek mode.

- RW media

CDSpeed graph

For the RW reading tests we used Mitsubishi Chemicals 24x US-RW and 32x US-RW media (Mitsubishi Chemicals 97m34s25f, 74:43:00). However, the drive was not able to recognize the 32x US-RW media. Consequently, we had to run the tests by using the 24x discs only.

Mitsumi CR-48XFTE did not read the disc at the maximum 54x speed. The drive started reading at 18.2x and finished the task at 41.15x, resulting to an average speed of 31.16x. In the same test, the Premium drive was faster (SpeedRead enabled), while Optorite CW5201 performed in a way similar to the Mitsumi drive.
