Nah, Panasonic's LF-PB271JD couldn't hold a candle to Sony's BWU-200S
in a runway competition, but when it comes to performance, we'd say the two are practically neck and neck. This unit fits snuggly within any Windows-based machine lookin' for a 5.25-inch optical drive, and it has no problems burning dual-layer BD-Rs at a furious (ahem) 4x pace. Additionally, you'll find a SATA interface along with backup software bundled in, and just in case you're not working exclusively with BD-R, it can also toast BD-RE at 2x, DVD±R at 16x, DVD±R DL at 8x, DVD-RW at 6x, CD-R at 40x and CD-RW at 24x. Of course, you'll be paying through the nose for the luxuries presented when it lands on November 10th, but the ¥55,000 ($468) asking price is still a good bit lower than what Sony's demanding.
