"LG offers flexibility to consumers in the next-generation in optical disc drives. The GGW-H10N is compatible with both Blu-ray Discs and HD-DVD formats. The Super Multi Blue drive is compatible with Blu-ray Disc, DVD, CD read/write and HD-DVD-ROM (read), offering consumers the most universal unit available. The GGW-H10N can record up to 50GB of data, equivalent to 4-1/2 hours of high- definition video or 22 hours or standard definition video (on a dual layer 50GB BD-R/BD-RE recordable media). Surpassing the market standard, LG is providing a 4x recording speed of Blu-ray Discs, which means that it takes only 23-24 minutes to burn a full single layer BD-R disc (25GB), compared with 46-47 minutes for conventional 2x recording."
