| Interface and mechanical fit | Internal Serial ATA (SATA), 5.25-inch half-height desktop mechanism. Confirm connector, front bezel, mounting screw positions, clearance and supply before installation; do not treat this summary as a dimensional drawing. |
| Host compatibility | Internal 5.25-inch SATA PC drive with SATA data/power and compatible motherboard/controller/OS optical support. Blu-ray playback and authoring need software/codec/protection support. M-DISC requires compatible media and correct recording software; verify model/firmware and exact media logo. |

Host setup and preservation notes
- Verify the exact drive label, firmware, SATA data/power connection and optical-device enumeration before testing media. Old vendor OS lists describe tested software at release, not a modern support guarantee.
- Read support is not write support. Use media bearing a format the exact drive/firmware supports; distinguish BD-ROM, BD-R and BD-RE, and do not infer BDXL/UHD capability from the Blu-ray logo alone.
- For preservation reads or recordings, log drive model/firmware, host controller, OS/software, media type, checksums and read/verification errors. Keep original discs unmodified and store them in protective cases in a clean, cool, dry location.
