Data CD Tests
- Pressed CD results
(80min CDSpeed
graphs)
The LG drive supports a maximum reading speed of 32x for the
CD-ROM format. The reading method used is CAV and in our tests, the disc was
read successfully, reaching a final speed of 33.07x with an average of 25.06x.
We feel that the LG drive could offer higher reading speeds in roder to compete
with the other burners available on the market.
The seek times for the pressed disc are a little on the slow side, especially the full seek time which took 238ms.
- CDR Media results
(80min CDSpeed
graphs)
The pressed disc used in the previous test was copied onto CDR
media and the drive was tested again for reading speed and seek times. The final
speed reached was 33.24x and the average speed was 25.16x.
The CDR media seek times for the LG GSA-4081B produced figures
similar to those for pressed media, where the random and 1/3 seek times were
average, but a full seek needed a hefty 255ms. With both types of media, the
performance is very similar, there not being much between them in either speed
or seek time.
- HS-RW media
(HSRW
CDSpeed )
For the RW media reading test we used a 24x MC HS-RW
disc. The LG drive supports 24x reading speed for CD-RW media and as can be
seen from the following graph, it confirms this reaching a final speed of 25.16x.
