[ OPTICAL DRIVES // IDENTIFIED EXTERNAL MODEL ]
LG BP50NB40
Ultra-slim USB Blu-ray/DVD writer with BDXL and M-DISC support. Use the exact BP50NB40 model label when matching media, firmware and host software.
IDENTIFICATION: Confirm the full model/suffix against the label and manufacturer documentation. Read capability is not write capability; speed ratings depend on media and recording mode.
Model-specific specifications
| Catalog subcategory | External Blu-ray drives |
|---|---|
| Exact product identifier | LG BP50NB40 |

Host and media notes
BP50NB40 is a portable external drive, not an internal slimline mechanism; confirm media layer and application support rather than assuming every supported read format is writable at the same rate.
- Use the drive only with media types explicitly supported by the exact manual. BDXL, standard BD-R/RE and UHD Blu-ray are distinct capabilities.
- Check operating-system and playback/authoring application support independently; a USB connection alone does not provide Blu-ray codec, protected-video or UHD playback capability.
- For preservation work, record drive model/firmware, host interface, software, media type, checksums and read/verification errors with each image.
