The DH401S is LiteON's latest internal Blu-ray drive and the company's second drive that carries the "Blu-ray disc" logo, after the LiteOn LH-2B1S BD burner. However, this drive is a BD-ROM device and supports reading of all the CD/DVD/BD media currently available, except from the DVD-RAM. LiteON has already released in the US another version of the DH401S drive supporting reading of DVD-RAM discs.

Reading speeds of BD media are set high enough. Specifically, the drive can read all of the BD types at 4X. DVD±R media can be read at 12X, DVD±R DL at 8X, and DVD±RW at 8X.
