DVD+R and Dual-Layer Write Testing

CD/DVD Write Performance Testing
Pushing it to 16X

Nero CD-DVD Speed - DVD+R Write Test:

Again, we repeated the process, this time with DVD+R media in each drive.

Plextor PX-712SA

Each drive used P-CAV during the process, although each produced a very different picture.  The ASUS DRW-1604P had a stepping pattern as the drive increased its speed as it progressed through the test.  With the Plextor drive, this pattern was similar, but leveled off as it reached its 12X peak faster than the ASUS reached its 16X.  In fact, the ASUS drive hit 16X at the very end of the test, barely registering on the chart.  Overall, both drives averaged over 10X, with the Plextor model running slightly faster, resulting in a completion time of 6:16 minutes, compared to the DRW-1604P's time of 7:11 minutes, almost 1 minute longer than the slower rated drive.  We're fairly certain the Plextor drive is benefiting somewhat from its 8MB cache compared to the DRW-1604P's 2MB buffer.

Nero CD-DVD Speed - DVD+R/Dual Layer Write Test:

Our last test will demonstrate the ASUS DRW-1604P's Dual Layer performance.  The Plextor PX712A doesn't support Dual Layer, so no comparison was available.  However, this still gives us a good idea of what the ASUS model can achieve.


Using Constant Linear Velocity, the ASUS DRW-1604P managed a steady 4.01X throughout, with a minute dip at the mid-way point.  The overall process completed in 27:08 with a full 8GBs written.
