Plextor PX-B940SA 12x Blu-ray Disc Writer Review

To test the CD read performance we are using CD WinBench 99 and CD Speed. Nero Burning Rom is used to write 700MB to our optical media.

CD Reading:


CD Winbench is a great ‘real world’ test, as it uses eight different applications which are activated by scripting.

The Plextor drive started reading the media at around 14x and then hit a maximum speed of 38x on the outside of the optical media.

Next, we used a CD containing one Mode 1 data track. The disc is around 74 minutes in length and has a mixture of data and folders, in keeping with a data structure many of us would have on a hard drive.

Random access times access time (lower is better)
Plextor PX-B940SA 142ms
Pioneer BDR-2203 114ms
Sony BWU-300S 140ms
CPU demand (8x) percentage (lower is better)
Plextor PX-B940SA 12%
Pioneer BDR-2203 7%
Sony BWU-300S 5%

When writing CD’s the Plextor PX-B940SA has the worst access time and demands the highest amount of processor time. Its nothing critical, but worth noting.

CD Writing:

It took the Plextor drive 3 minutes and 12 seconds to write 80 minutes of data which is a very good result. The Sony BWU is the class leader however with CD media and it took only 2 minutes and 51 seconds. The Pioneer drive took last place with 3 minutes and 54 seconds for complete mastering.
