LG BU40N Ultra Slim Blu-ray / DVD Writer 3D Blu-ray Disc Playback & M-DISC Support

The LG BU40N is an internal optical drive that reads and writes Blu-ray, DVD, and CD media while taking only 9.5 mm of vertical space inside a notebook bay or small form factor desktop. It connects through a SATA 3.0 interface, so data moves quickly whether you are watching a UHD 4K film, burning a family video archive, or installing software from legacy discs.

With Blu-ray read and write speeds that reach 6× and DVD speeds up to 8×, the drive completes backups and disc creation tasks without long waits. CD projects move even faster at 24×. A 4 MB buffer, combined with under-run prevention, keeps the process smooth so you do not waste blank media.

For home entertainment, the BU40N supports UHD 4K and 3D Blu-ray playback. Jamless Play steps in when it encounters scratches or fingerprints, automatically jumping past damaged spots to maintain uninterrupted viewing. When silence matters, such as during late-night movie sessions or in a quiet office, Silent Play reduces operational noise.

M-DISC compatibility gives creators, photographers, and small businesses a way to store important files on discs designed for long-term stability. Whether you are building a compact HTPC, upgrading a work laptop, or outfitting a slim mini-PC, this drive provides a versatile solution without adding bulk.
