2. Data Tests

Sony CRX 210E1 IDE CD-R/RW- Page 2

Data Tests

- Notice: To create the graphs, we used both the default reading speed (40X) and the (48X) with the activation of the "turbo mode".

- Pressed CD results: (Click to see the CD Speed Graph for 40X & 48X)

We compare the reading speed performance of the Sony CRX-210E1, PlexWriter PX-4824A and Cyberdrive CW088D. The Sony and Plextor drives support optional 48X maximum reading speed. We set the 48X speed for both drives and it seems that Sony CRX-210E1(36.89X) is faster than the PX-W4824A (35.66X), and slightly faster than Cyberdrive CW088D. In the 40X maximum reading speed, the Plextor drive is 0.3X faster than the Sony.

The seek times of Plextor and Sony does not seem to be affected by the maximum read speed set (40X or 48X). The faster drive is Plextor with approximately 65 msec for the Random seek mode, and 114 msec for the Full mode. Sony CRX-210E1 has the second best performance with 84 msec for Random and 142 msec for Full modes.

- CDR Media: (Click to see the CD Speed Graph for 40X & 48X)

With CD-R media, Cyberdrive CW088D is faster with 37.52X, leaving Sony CRX-310E1 in the second position with 35.71X, in the in the 48X test. The Plextor drive follows closely with 35.71X.

The seek times with the CD-R disc have not changed for all the drives, with PlexWriter PX-W4824A to lead with 63 msec for the random seek mode.

- HS-RW media: (Click to see the CD Speed Graphs)

For checking the performance of the drives with rewritable media, we used the HS-RW from Ricoh. Sony CRX-210E1 is fast and takes the first position with 31.87X. The Plextor drive follows with 31.44X and Cyberdrive gets the third position with 30.82X. There were no difference in the average reading speed of the Sony drive with the 40X or 48X speeds selected.
