Sony Unveils 4X Blu-ray Disc Burner

16 Comments
Sony on Tuesday announced its second-generation Blu-ray disc burner for computers, which doubles the speed of its predecessor to 4X. The BWU-200S can record a full 50GB disc in 45 minutes, and also improves upon standard DVD+R burning speed, which is now at 16X.
Like early-generation CD and DVD burners, however, Sony's new model won't come cheap. The BWU-200S carries a price tag of $600, which includes CyberLink's Blu-ray burning software, and 50GB BD-R discs run upwards of $30 a piece for 2X versions. The drive features a Serial ATA interface and works with Windows Vista and XP.
