BluRay Reading:
To test the Plextor PX B940SA's BD ROM read performance we used the Blu Ray disc version of Avatar.
| Random access times | access time (lower is better) |
| Plextor PX-B940SA | 78ms |
| Pioneer BDR-2203 | 69ms |
| Sony BWU-300S | 92ms |
| CPU demand (8x) | percentage (lower is better) |
| Plextor PX-B940SA | 3% |
| Pioneer BDR-2203 | 3% |
| Sony BWU-300S | 2% |
The PX B940SA performed well with the BD-ROM disc test. The software bundled works fine with this disc, although we would recommend you pay a little extra for the updated version of PowerDVD.
Next we used a Maxell BD-R disc to measure read performance.
| Random access times | access time (lower is better) |
| Plextor PX-B940SA | 76ms |
| Pioneer BDR-2203 | 83ms |
| Sony BWU-300S | 93ms |
| CPU demand (8x) | percentage (lower is better) |
| Plextor PX-B940SA | 3% |
| Pioneer BDR-2203 | 3% |
| Sony BWU-300S | 2% |
Again, very strong results from the Plextor drive, with the highest end disc performance, just shy of 8x.
Next we used a Panasonic BD-R Dual Layer disc to judge read performance.
The Plextor drive peaked around a maximum of 8x with our dual layer bluray disc test, which is very impressive, and ever so slightly faster than the Sony drive.
| Random access times | access time (lower is better) |
| Plextor PX-B940SA | 78ms |
| Pioneer BDR-2203 | 86ms |
| Sony BWU-300S | 95ms |
| CPU demand (8x) | percentage (lower is better) |
| Plextor PX-B940SA | 3% |
| Pioneer BDR-2203 | 3% |
| Sony BWU-300S | 3% |
The Plextor drive has been recording some of the best access times of all the drives on test today, and again, with Dual layer blu ray discs, it registers 78ms, faster than both Pioneer and Sony units.
BluRay Writing:
To test BluRay write performance we used BD-R and BD-R DL media from Memorex.
The Plextor drive is lightning quick when writing to BluRay media, clearly outperforming the other comparison drives today.
I always have been wondering about a blu ray burner, and if I really needed one. I keep buying hard drives for storage as they are so cheap now. Plextor make great products, this looks very good. price is a bit steep, thats 4TB of storage !
I have alwsys bought plextor. they cost more, but really worth it. they use the best components.
I haven’t opted for a blu ray burner yet. the discs are still quite expensive, hard drive space is cheaper. Maybe someday I will.
Id love one, but the disc prices still put me off. hard drives are so cheap right now. local store was selling a 2TB for only 60
