• CD-R Recording Times

For the burning tests we created an 80min data compilation through Nero Burning Rom, recording the data on a 700MB disc.

Below is a chart showing recording times with TraxData 52X media at various speeds compared with the other two drives.

The ASUS CRW 5232AS finished the task in 3:16 minutes, a little surprising for a drive with a maximum 52X writing speed.

The writing performance varies according to the inserted media, as our tests showed. Below is a chart demonstrating all recording times with various media.

The fastest recording time came with MMore 80min 52X media which took 161secs (2:41mins).

The ASUS supports the 16X, 24X and 32X P-CAV rewriting speeds, with Ultra Speed Rewritable Media (US-RW).

Below you can see the Nero CD-DVD Speed writing simulation test with blank 32X US-RW media from Verbatim.

The drive starts the writing task at 20.23X and reaches the maximum 32X at the 25:00 min address mark on the disc. According to CDSpeed, the average writing speed is 29.61X.

We also used Nero Burning Rom in order to burn a data disc with 32X US-RW media from Verbatim. The data compilation we burned had a size of 651 MB and the duration of the recording process was 2:57 minutes.
