Product Description
The Lite-On DH-20A4P-21C is an internal optical drive designed to provide comprehensive CD and DVD read/write functionality for desktop computers. With a maximum DVD write speed of 20x for both DVD+R and DVD-R formats, users can quickly burn full discs of data, video, or audio. The drive also supports rewriting capabilities, offering 8x for DVD+RW and 6x for DVD-RW media, along with 5x for DVD-RAM, providing flexibility for data archiving and temporary storage needs. This drive is particularly notable for its support of double-layer (DL) media, allowing for higher capacity discs (up to 8.5GB) compared to standard single-layer DVDs (4.7GB). This feature is essential for burning larger video projects, extensive backups, or software installations that exceed the capacity of a single-layer disc. The drive's SATA interface ensures a high-speed connection to the motherboard, facilitating efficient data transfer during read and write operations. Equipped with buffer under run protection technology, the DH-20A4P-21C minimizes the risk of coasters (failed burns) caused by data transfer interruptions. It also offers robust read speeds, including 20x for DVD-ROM and 48x for CD-ROM, making it efficient for accessing existing optical media. Housed in a standard 5.25-inch bay, this drive is a versatile addition for any PC requiring reliable optical disc burning and playback capabilities.
