Slim Blu-ray Writer with USB 2.0

The LG WP50NB40 is a new external optical drive that reads and writes BD-R, BD-RE, DVD and CD media. It connects through a USB 2.0 interface and fits a slim form factor for portable use. The unit includes a 4 MB cache to buffer data during disc operations.

Suits users who need Blu-ray writing on a laptop

Buyers who require faster than 2.0 transfer rates should look elsewhere. The drive reaches 6x BD write, 8x DVD write and 24x CD write speeds, which meet typical archiving and playback needs for physical media collections.

USB 2.0 host interface

This single specification decides whether the drive matches the available port on the target machine. The interface determines the maximum sustained throughput for all read and write operations listed above.
