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.
