LiteOn's second generation of Blu-ray burners is the new DH-4B1S. Its manufacturers call it "Triple Writer", meaning that it can burn all types of optical storage media currently available (except for DVD-RAM). BD-R burning speed is set at 4X which is a good speed - although not the best that you can fnd on the market.The drive can be connected to any PC using a Serial-ATA interface, ensuring that data transfer will never slow down the process of BD reading/playback.

The drive can burn BD-RE media at 2X, DVD±R media at 12X, DVD±R DL at 8X, DVD+RW at 8X, DVD-RW at 6X, CD-R at 40X and CD-RW at 24X.

Reading speeds are also set high, with the DH-4B1S being able to read BD-ROM media at 4X, DVD-ROM media at 12X and CD-R/RW media at 40X.
