What the Measurement Means
This function reports the read response of the Plextor PX-712 drive. The
graph should display a smooth linear curve up to the limit of the
recorded data. If the curve is not linear or smooth, repeat the test with
another piece of recorded media. Most read transfer failures are caused
by poor quality or damaged media.
Measuring Write Transfer Rate
The Write Transfer Rate selection lets you test the transfer rate of data
written to a disc. The function reports the writing response of the Plextor
PX-712 drive. This test is conducted on blank media to determine the
capabilities of the drive/media combination.
To measure write response:
1. Place a blank recordable or rewritable disc in the Plextor PX-712
drive. You can use a blank DVD+R or +RW disc, a DVD-R or -RW
disc, or a CD-R or CD-RW disc.
2. From the PlexTools menu bar, select Write Transfer Rate Test. You
see the Write Transfer Rate Test window with a graph for write
speeds.
3. Select the speed pulldown menu and choose the desired transfer
speed.
