Multi-Function USB DVD Drive: Most new laptops and desktop computers no longer come equipped with built-in optical drives, LAN ports, or SD/TF card slots, and USB ports are often insufficient. Our external cd/dvd drive for laptop features 1 USB 3.0 port, 1 USB 2.0 port, 1 Type-C port, 1 LAN port, 1 TF card slot, and 1 SD card slot—perfectly addressing these limitations. (Note: Strongly recommended to use with power cable; SD and TF card slots cannot be used simultaneously.) LAN Interface: The rear of the external cd dvd drive for laptops features an Ethernet port (for connecting the device to a local area network). This transforms the cd burner into a centralized network-shared optical disc device, enabling other devices to access, read, or burn discs without repeatedly plugging and unplugging equipment. It also facilitates data transfer and communication within your local area network, enabling resource sharing High-Speed USB 3.0 & Type-C Port: The external dvd burner features an embedded 2-in-1 cable design on its rear panel, equipped with both USB 3.0 Type-A and Type-C ports. This eliminates concerns about misplacing cables and allows seamless connection to various devices without additional adapters. The external cd/dvd drive's cable utilizes USB 3.0 technology, delivering data transfer speeds up to 5Gbps (625MB/s)—approximately 10 times faster than USB 2.0
