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

Rating: 8.0.

Blu Ray writers are finally starting to come down in price and today we are reviewing the Plextor PX-B940SA drive. Plextor have been producing some of the finest drives on the market for the last decade and their optic quality has always been a primary selling point.

With HD-DVD resigned to the annals of history, BluRay as a platform is dominating the market.

Over the last few years Plextor have produced many great players. The PX-B940SA we are reviewing today is their first 12x BluRay drive. The technology in this unit is based around the Pioneer BDR-205 drive, but the PX-B940SA is capable of 12x BD-R, 12x BD-r DL and 2x BD-RE writing speeds with a maximum BD-ROM speed of 8x.

This Plextor PX-B940SA is also backwards compatible with all major DVD and CD formats and is supplied with a substantial 4MB buffer and a software suite from industry leader Cyberlink.

  1. 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 !

  2. I have alwsys bought plextor. they cost more, but really worth it. they use the best components.

  3. 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.

  4. 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
