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.
