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

DVD Reading:

We used a single layer Verbatim DVD disc for these tests: 4.37GB in size.


Random access times access time (lower is better)
Plextor PX-B940SA 148ms
Pioneer BDR-2203 150ms
Sony BWU-300S 153ms
CPU demand (8x) percentage (lower is better)
Plextor PX-B940SA 10%
Pioneer BDR-2203 5%
Sony BWU-300S 3%

Plextor’s drive put in a good showing when reading single layer DVD ROM discs, maxing at 15.98 x at the end of the disc.

Next we used 16x Vertabim DVD R media to test drive read speed.

Random access times access time (lower is better)
Plextor PX-B940SA 158ms
Pioneer BDR-2203 161ms
Sony BWU-300S 166ms
CPU demand (8x) percentage (lower is better)
Plextor PX-B940SA 10%
Pioneer BDR-2203 6%
Sony BWU-300S 4%

The Plextor drive lives up well to the speed claims performing alongside the Pioneer BDR-2203 drive. The Sony BWU-300S is the clear leader again in this test.

Next we used Verbatim DVD Dual Layer media to test drive read speed.

Random access times access time (lower is better)
Plextor PX-B940SA 173ms
Pioneer BDR-2203 175ms
Sony BWU-300S 164ms
CPU demand (8x) percentage (lower is better)
Plextor PX-B940SA 7%
Pioneer BDR-2203 4%
Sony BWU-300S 5%

The PX-B940SA lives up to claims when reading DVD-R and DVD DL media. It exceeded the 16x speeds for DVD R discs and more than 12x for dual layer discs.

DVD Writing:

To test the Plextor DVD writing performance we used Verbatim 16x DVD+R and 8x DVD +RW media. To achieve write times we used a 4.38gb image file burned via Nero software.

A good set of results for the Plextor drive measure over 6x recording for +R media and over 7x recording for +RW media. The Sony drive struggled a little with the +R recording, dropping to 5.52 x.
