Conclusion: Let us summarise the most important positive and negative points below: The Sony BWU-300S performed extremely well in our tests. BD-R writing performance was excellent and the fastest Blu-ray drive we have yet tested. The Sony BWU-300S was able to burn all our tested CD-R/RW media with excellent/very good quality. What is more, the Sony BWU-300S offers extremely fast CD-R writing speeds, and in some cases faster than dedicated CD-RW burners.
Pros: Fast Blu-ray burning performance at 8x max., Excellent CD-R writing performance, Very good DVD burning performance., Very good DVD±R DL writing performance for a Blu-ray burner., Excellent/very good DVD±R writing quality., Excellent/very good CD-R/RW writing quality., Supports DVD-RAM read and write at 5x., Supports BitSetting (BookType DVD-ROM) on DVD+R DL., Good software package., Near silent operation when playing back BD and DVD movies.
Cons: Slow ripping speed of CD-Audio/DVD-Video/BD-Video, Doesn’t support BitSetting for DVD+R/RW, Burned some CD-R and DVD R media slower than its rated writing speed., Expensive
Conclusion: It has been nearly two years since I reviewed Sony's first Blu-ray Disc writer, the BWU-100A. Since then, companies like LG and Pioneer have raised the bar, introducing drives with new features and faster BD writing speeds. With the BWU-300S, Sony has risen to the challenge. Based loosely on the Panasonic SW-5584, the drive offers good looks, a number of useful features and some of the fastest BD reading and writing speeds available.
Pros: Writes to BD-R and BD-R DL media at 8x, Writes to BD-RE media at 2x, Writes to DVD-R and DVD+R media at 16x, Writes to DVD+RW media at 8x, Writes to DVD-RW media at 6x, Writes to DVD+R DL and DVD-R DL media at 8x, Reads single layer BD-ROM's at 16x, Reads BD-R and BD-R DL media at 6x, Reads single layer DVD-ROM's at 16x, Reads DVD±R media at 16x, Reads DVD±RW and DVD±R DL media at 8x, Features 48x CD-R and 24x CD-RW writing speeds, 8MB buffer, Good CD-R writing qualit...
Cons: High media requirements when writing to BD-R and BD-R DL media at 8x, Questionable writing quality with some DVD±R and DVD+R DL media, Had a hard time reaching its rated CD read speeds, Reads BD-RE media at only 2x, Reads DVD-Videos at only 6x, Rips audio CD's at only 24x, Cannot set the book type of DVD+R and DVD+RW media, Expensive
Summary: It’s that particular. So in real-world terms we’re really looking at a drive that performs about the same, or marginally worse, than LG’s GBW-H20L, yet costs $100 more. Even the bundled Men in Black BD disc doesn’t justify that premium. Heck, we’re not convinced that Blu-ray is worth even the lower price.
Conclusion: The Sony BWU-300S left us with a good overall good impression. The drive can be used for fast backups of data on Blu-ray discs, as well as for entertainment allowing you to watch your favorite BD movies on your PC or HD screen. We hope that the writing quality with some DVDs as well as compatibility with more BD media can be easily improved through firmware updates, making it a true competitor of the other 8x BD burners out there such as the Pioneer BDR-203.
Excerpt: Almost as disappointing is the lack of progress in the format's specifications. Like the Buffalo and Pioneer BDR-203BK , the Sony BWU-300S lists support for eight-speed BD-R. But media that can support this speed is still nigh impossible to buy. Indeed, even six-speed media continues to prove elusive to most consumers. We tested the drive with Sony's own six-speed and quad-speed Verbatim BD-R media.
