The new LG GBW-H10N fared a lot better in this aspect than the few early Blu-ray drives in the market, but it is still not the perfect Blu-ray solution despite its ability to burn BD-R media at an unprecedented speed of 4x. This positive achievement was dampened by the drive's lack of support for dual layer Blu-ray. A single layer 25GB Blu-ray disc support is the most you can hope on this LG drive though we are not sure if a future firmware update will add support. Fortunately, compared to the very first Blu-ray drives, which had only DVD/Blu-ray support, the LG at least supports writing to all existing formats, including less popular ones like DVD-RAM, though write speeds are not as fast as most consumers are used to.
