The "Golden Standard" for Ripping: It is considered the most reliable version for creating 1:1 ISO backups. Enthusiasts often find that it avoids specific "read errors" or timeouts that plague newer stock firmwares. Reliable Speed
: While some internal LG drives can burst to 8x, they often fluctuate. The bu40n 100 firmware hot

The BU40N is an LG/HL DS (Hitachi-LG) slim internal Blu-ray drive. The "100" likely refers to firmware version 1.00 (or a similar early build), which is often sought after because earlier firmware versions (1.00, 1.01, 1.02, 1.03) are friendly for LibreDrive and can be flashed to enable UHD (4K Blu-ray) ripping.
